Adam -- a primal Old Testament name -- was revived as a 1960s cowboy name. Adam is not as popular as it once was and feels ready for a respite, replaced by newer A names like Aidan/Aiden, Avery and Axel. Its most prominent current bearers include Adams Sandler, Levine, Brody and Driver -- who plays a character named Adam on Girls.
 Adam, of course, is the first man God created. It is also a generic term for mankind. Adam did not hit the U.S. Top 100 until 1970, peaking in the early '80s at Number 18.

Adam

Alaric is an ancient regal name that sounds modern enough to be considered. Alaric was a traditional name for the kings of the Ostrogoths, the most famous of whom was Alaric I, the King of the West Goths who sacked Rome in 410. 
 In literature, Alaric was a noble character in P. G. Wodehouse's Blandings Castle novels, the lead character in Alexander Theroux's Darconville's Cat, appeared in Stephen King's The Dark Tower series, and was the name of a history teacher on The Vampire Diaries.
 More unusual than Frederic or Roderic, Alaric could make a quaintly quirky path to all the Al and Rick nicknames.

Alaric

Albert has acquired a new gloss as one of the top <a href="https://nameberry.com/list/341/royal-names-for-boys">royal baby boy names</a>, a considerable upgrade from its serious, studious image (think Einstein, Schweitzer). 

Albert became popular in Britain following the 1840 marriage of Queen Victoria to the German Prince Albert and remained in vogue for 80 years. In the US, it's been on a downward slide for a century, though it's always ranked in the US Top 1000 and is a Top 100 name in England and Denmark.

Along with such stalwarts as Walter and George, it could now make a distinctive yet classic choice. Enlivening nickname Bertie is popular on its own in the UK.

Albert

Alois and Aloysius are variation of Louis. Alois ranked in the US Top 1000 until the 1930s, and still ranks in the Top 1000 in Germany. Last year in the US, only seven baby boys were named Alois.

Alois

Alvertos

Cultured and cultivated in an old-style, Old World way. Sometimes associated with the classic writer Anton Chekhov. Al Pacino has a son with this name.

Anton

Though this name is rooted in Greek mythology, it just entered the US Top 1000 for the first time in 2013, but as one of the year's fastest-rising names.

 In Greek mythology, Ares was the blood-thirsty god of war and son to Zeus and Hera. Names from ancient myth and legend are generally on the rise, as is evidenced by Gwen Stefani's choice of Apollo for her third son.

Ares

Quirky cool Arlo is now well and truly back. Last year it broke into the US Top 200 boy names and consistently ranks among the most popular boy names on Nameberry. 
 Arlo is even more popular in the UK, Australia and New Zealand. Arlo is also one of the top baby names among Nameberry's visitors from leading US cities.

 
Once strongly associated with shaggy singer Arlo Guthrie, Arlo has an animated and cheery feel, thanks to its upbeat o ending. It was chosen by Toni Colette for her son in 2011, which brought the name back into the spotlight. Previously, Arlo was in regular use in the first half of the twentieth century—it was Number 667 in 1915, for example, but it had dropped off the charts in 1944.
 Arlo has many possible derivations along with its Irish and English roots. It may be a shortened form of the Italian name Carlo or the Spanish Carlos, and in Basque-speaking regions it is the word for area. In English, Arlo was used as a place name, Arlo Hill, by Edmund Spenser in his epic poem The Faerie Queene and is thought to derive from the Celtic word Aherlow, meaning "between two highlands."

 A growing number of girls are also named Arlo in the US each year, with a handful more babies of both sexes receiving the Arlow and Arlowe spellings, which take this name more into smart surname territory.

Arlo

Arthur, once the shining head of the Knights of the Round Table, is, after decades of neglect, now being polished up and restored by stylish parents, inspired perhaps by the new generation of royals. Arthur has led the list of possible names for the young British princes, chosen as a middle name for Prince Louis, son of William and Catherine, Prince and Princess of Wales.
 In addition to its leading role in the Arthurian legends, Arthurs figure prominently in Nathaniel Hawthorne's The Scarlet Letter, Edgar Allan Poe's The Narrative of Arthur Gordon Pym of Nantucket and George Eliot's Adam Bede. There are also countless Arthurs in children's literature, movies, and TV -- including The Fonz of Happy Days fame. More recently, Arthur was the son of Mr. and Mrs. Santa in the eponymous movie Arthur Christmas.
 Arthur has many notable namesakes, including playwright Arthur Miller; writer/astronomer Arthur C. Clarke; writers Arthur Conan Doyle, Arthur Rimbaud and Arthur Koestler; philosopher Arthur Schopenhauer; conductor Arthur Fiedler; and tennis great Arthur Ashe, the first African American to win the U.S. Open. Queen Victoria's seventh child was Prince Arthur.
 Arthur was a Top 20 name from at least 1880 through 1926. And in 2011, actress Selma Blair named her son Arthur Saint.

Arthur

The name August is at its highest point since the 1890s, when it ranked among the Top 100 boy names in the US. And deservedly so, given its great meaning, historic roots, and cool nicknames.
THE celebrity baby name of the moment, August was chosen by both Princess Eugenie and Mandy Moore for their baby boys in early 2021. Before that, August had been heating up in Hollywood – used by Mariska Hargitay and Peter Hermann, Lena Olin, Dave Matthews and Jeanne Tripplehorn for their sons
August is the only truly popular month name for boys. The month of August was named after the Emperor Augustus.
 August has two august literary namesakes: the Swedish playwright August Strindberg (it has always been a popular name in Scandinavia), and August Wilson, as well as photographer August Sander.
 The French version is Auguste (ow-GOOST), as in Edgar Allan Poe's clever detective Auguste Dupin and famed sculptor Auguste Rodin.

August

Parents are beginning to look at imposing, somewhat fusty-sounding names like this one with fresh eyes: they definitely make a strong statement.
 Augustus originated as a title given by the Roman Senate to the first Roman Emperor, Octavian, the adopted son of Julius Caesar, in 27 B.C. and adopted by him as a name. In the U.S., Augustus reached a high of Number 175 in 1880, fell off the list in 1970, then made a return appearance in 1991, and is now on the rise once more. 
 Augustus Snodgrass is a character in Charles Dickens' novel The Pickwick Papers, and George Bernard Shaw wrote a play titled "Augustus Does His Bit." Augustus John was a famed British portrait painter, and Augustus Saint-Gaudens a well-known sculptor.
 No starbaby Augustuses as yet, but Dixie Chick Emily Robson used Augustus as a middle name for her son, and Dan Aykroyd did the same---for his daughter.
 The diminutive form, Augustine, is also an interesting option; variant Augustin was used by model Linda Evangelista; and then there is always über-popular August.

Augustus

Benjamin is a biblical name that has enjoyed widespread favor for decades, ranking in the US Top 50 for almost half a century and the Top 10 from 2015 until 2023. 

One of those golden boys' names that feels traditional as well as sensitive and stylish, Benjamin has the further advantage of the friendly, accessible nickname Ben.
Benjamin is hugely popular not just in the US but in a range of other western countries, including France and Germany along with Scandinavia and Latin America. The names Benjamin and Ben will be familiar around the world.
 Benjamin is derived from the Hebrew name Binyamin, from the elements ben, meaning "son" and yamin, "right hand." In the Old Testament's Book of Genesis, Benjamin was the youngest of the twelve sons of Jacob and Rachel and he was one of the founders of the twelve tribes of Israel. 
 
There have been numerous notable Benjamin namesakes, from Benjamin Franklin to Dr. Benjamin Spock. The name's popularity spiked after the release of The Graduate in 1967, with Dustin Hoffman playing the iconic Benjamin Braddock.
 Benjamin is the name of the sons of Kelly Preston and John Travolta as well as of Gisele Bundchen and Tom Brady.

Benjamin

Benno is a cool name in its own right -- there was a tenth century Saint Benno -- though it is also used as a lively nickname for Benjamin. Saint Benno of Meissen is the patron saint of anglers and weavers and, strangely enough, alliteration.
 Benno came to attention in the U.S. via the father and son duo of Benno Schmidt Sr. and Jr. Senior was the venture capitalist who invented the term venture capitalist and Junior was the president of Yale University. Benno is also the appellation of a student character in Umberto Eco's The Name of the Rose.

Benno

This ancient name, also spelled Caspar, is finally shedding its ghostly image and moving into the 21st century. Popular in the Netherlands and Scandinavia, where it's sometimes shortened to Cas, Casper could ride the style coattails of cousin Jasper.
Casper was one of the Three Magi who brought gifts to the infant Jesus along with Melchior and Balthasar.
 Some notable Caspers are one-time Secretary of Defense Casper Weinberger (called Cap) and actor Casper Van Dien, whose son is Casper Robert Van Dien III. Claudia Schiffer and Jenny Frost both used the names for their boys, while Jason Lee did a gender switch when he called his daughter Casper (sister of Pilot Inspektor).
 Casper Goodwood was the persistent suitor of the main character, Isabel Archer, in Henry James's novel A Portrait of a Lady.

Casper

Cedric was invented by Sir Walter Scott for the noble character of the hero's father in Ivanhoe, presumed to be an altered form of the Saxon name Cerdic. The name was later also given to Little Lord Fauntleroy, the long-haired, velvet-suited, and lace-collared boy hero of the Frances Hodgson Burnett book, who became an unwitting symbol of the pampered mama's boy.
 Since then that stereotype has been broken principally by the handsome Harry Potter character Cedric Diggory, played by the teen-aged pre-Twilight Robert Pattinson, and it, like cousin Cecil, is at the point of being rediscovered by cutting-edge namers.
 Actor and comedian Cedric the Entertainer has propelled this name into the spotlight in recent years.
 Cedric has been on and off the charts the last few years, but is currently back in the Top 1000 in 2022.

Cedric

The sophisticated Edmund and its nearly-identical French twin Edmond are coming out of mothballs now that Edward, inspired by Twilight, is once again a hot name.
 Edmund has had an enviable history, as evidenced by these quotes: "There is nobleness in the name of Edmund," says a Jane Austen character, and the poet John Keats once bemoaned, "Had my name been Edmund, I would have been more fortunate."
 Famous bearers include the English astronomer Edmund Halley, after whom the comet was named, poet Edmund Spenser, great Shakespearean actor Edmund Kean, and New Zealand mountaineer Sir Edmund Hillary. Literary Edmunds appear in King Lear,, Jane Austen's Mansfield Park, and Dickens's Little Dorrit.
 Edmund reached its highest point of popularity in the U.S. in 1914, when it was Number 130; it hasn't appeared on the list since 1997--making it even more attractive as an uncommon alternative to Edward.
 Eamon is the cheery Irish version.

Edmund

Elmo, like fellow Sesame Street characters Kermit and Grover, has a hard time being taken seriously. (It isn't easy being red either.)
 But Elmo also calls to mind the image of St. Elmo's fire--the light show sometimes visible around ships' masts during storms at sea, which is quite appropriate since Saint Elmo (another name for Erasmus) is the patron saint of sailors. St. Elmo's Fire was also the title of a classic Brat Pack film of the 1980s.
 There were a lot more Elmos around a century ago, when Elmo was in the top third of the popularity list.

Elmo

Ezekiel used to be reduced to its nickname Zeke, but modern parents now embrace it in full for its power and dignity. Along with biblical brethren Asher and Ezra, Ezekiel is rising steadily up the popularity charts and is poised to take over for fading first wave Old Testament choices such as Zachary.
 Ezekiel is derived from the Hebrew name Yechezqel, composed of the elements chazaq, meaning "to strengthen," and ’el, referring to God. Ezekiel is a prominent prophet in the Old Testament and the author of the Book of Ezekiel, predicting the fall of Jerusalem and eventual rehabilitation of Israel. 
 
Ezekiel Cheever is a character in Arthur Miller's play The Crucible. An Ezekiel (nn Zeke) appeared on Wizards of Waverly Place, and is one of the Emanuel brothers to Rahm and Ari. 'Ezekiel' is a signature song of Harry Belafonte. 
 
Both Beau Bridges and Tisha Campbell-Martin have sons named Ezekiel. The growing stardom of Dallas Cowboys running back Ezekiel Elliot may push this name even higher.

Ezekiel

Ezra has a lot going for it: the strength of its heroic Biblical legacy, its quirky sound, and its fresh but familiar feel. Ezra is now at its highest point ever, but its intuitive streamlined spelling and deep roots could make it a worth successor to Elijah in the Top 10 -- or even to Liam or Noah at Number 1.
 Ezra just misses being among the elite group of male names that's always been in the US Top 1000, having dipped below the cutoff in 1964 and '67. Ezra also makes the Top 100 for boys in other English-speaking countries along with the Netherlands.
 Ezra is an abbreviation for the Hebrew phrase Azaryahu, meaning "Yah helps". In the bible, Ezra led a group of fifteen hundred Israelites out of slavery in Babylon and back to Jerusalem. 
 
Other notable Ezras include poet Ezra Pound and New York Times political columnist Ezra Klein. Ezra Cornell was a founder of Western Union and co-founder of the university that bears his name and Ezra Jack Keats is a popular children's book author-illustrator. 
 Both Paul Reiser and Taylor Hanson are dads to boys named Ezra, and there are Ezras to be found in Wilkie Collins's The Moonstone and Daniel Deronda by George Eliot.
 And let's not forget the band—Better Than Ezra—along with rising actor Ezra Miller, Vampire Weekend musician Ezra Koenig or the character Ezra Fitz from Pretty Little Liars.
 As unlikely as it may seem, Ezra is also growing in popularity as a girls' name, making the girls' Top 1000 in 2018 ad still rising. About 450 baby girls were named Ezra last year, but about 8000 baby boys, which puts Ezra below our 10% minimum to be considered a unisex name.

Ezra

Felix is one of those ancient but nontraditional names for boys that have come into favor over the past few decades, a favorite of parents who want a masculine name with history and heft that breaks ranks with the standard Franks and Freds. Felix is also an international darling, ranking in the Top 100 in several European and English-speaking countries.

Felix was originally a Roman surname but was adopted as a nickname by the ancient Roman Sulla, who believed that he was especially blessed with luck by the gods. It is the name of four popes and sixty-seven saints; in the Bible, Felix is a Roman procurator of Judea.
 
Felix, energetic and upbeat with a felicitous meaning, has finally transcended its negative associations to Felix The Cat and the persnickety Felix Unger. 
 
The name appears in literature as the central character in George Eliot's novel Felix Holt, the protagonist of Thomas Mann's Confessions of Felix Krull, in Thomas Hardy's Tess of the D'Urbervilles, Henry James's The Europeans, Kurt Vonnegut's Cat's Cradle, and as a member of the Volturi Guard in the Twilight series. In movies Felix has popped up in everything from several James Bond films to Spy Kids and The Hangover.
 
Gillian Anderson and Elizabeth Banks are two modern celebrities who chose Felix for their baby boys. A notable namesake is Felix Frankfurter, a long-term Supreme Court Justice.
 
Popular in the Hispanic community, Felix is also celebrating a surge abroad. Felix has been on the <a href="https://nameberry.com/popular-names">U.S. popularity list</a> for as long as records have been kept and is rapidly becoming a Nameberry fave.

Felix

Any number of Fitz names -- Fitzgerald, Fitzpatrick, Fitzroy, Fitzwilliam -- have been used as Christian names, in fact Fitzwilliam was the given name of the dashing Mr. Darcy in Pride and Prejudice. Fitz can be a short form of any of them and is often, like Mac, a nickname drawn from a surname.

Fitz

Gabriel has become a biblical favorite, an angelic choice that's lighter and less patriarchal than some of his Old Testament brethren. Derived from the Hebrew name Gavri’el, Gabriel is taken from the elements gever, meaning "strong," and ’el, in reference to God.
 
In Abrahamic religions, Gabriel is the archangel who heralded the news of Jesus' birth, and appears in Christian, Jewish and Muslim texts. He presides over Paradise, serving as the angel of mercy, life, joy, judgment, truth and dreams. 
 In addition to all his other responsibilities, Gabriel is the patron saint of broadcasters and diplomats, and he governs Mondays and the month of January, making Gabriel one of the top <a href="https://nameberry.com/list/629/71-wonderful-names-for-january-babies">January baby names</a>. 
 
Gabriel has proven itself a friendly and appealing alternative to Michael, that other, long-reigning archangel. Gabriel enjoys remarkable international popularity, ranking in the Top 100 in countries as diverse as Israel and Iceland, Chile and Croatia. It is currently the Number 1 boys' name in France.
 Parents of Gabriels of varying ages include Mick Jagger and Jerry Hall, Daniel Day-Lewis and Isabelle Adjani, Jason Alexander, Meredith Vieira, and Mia Farrow.

Gabriel

Though familiar to all via such childhood icons as Hans Brinker, Hans(el) and Gretel, and Hans Christian Andersen, few Americans have chosen this name for their sons because of its intractably Old Country image. 

Hans

The name of the last Anglo-Saxon king of England before the Norman conquest, and a name that's long been associated with a pipe-smoking, bespectacled grandpa or uncle.
 
After years in style limbo, Harold is slowly making a comeback, possibly boosted by cheerful nicknames like Harry and Hal. Filmmaking couple Greta Gerwig and Noah Baumbach have a son named Harold.

Harold

A bit stiff and formal for American use. 

Hendrik

Henning

Henry is back. The classic Henry climbed back onto the Top 10 in the US in 2021 for the first time in over a century, and now stands at Number 8.
 Like James and Theodore, Henry is a traditional name that also manages to feel stylish. Despite its popularity, it's not for everyone, but in some upscale American suburbs, it can seem as if every other little boy is named Henry or Theo or Jack.
 Henry was derived from the French Henri, which ultimately comes from the Germanic name Heimrich, made up of the components heim, meaning "home" or "estate," and rich, meaning "ruler." The most famous bearer is Henry VIII of England, best known for having six wives—two of whom he beheaded for not bearing him sons. It’s been used in the British royal family many times since, including for the current prince better known as Harry.
 
Other illustrious Henrys that might provide baby name inspiration include Henry David Thoreau, Henry (Hank) Aaron, Henry James, Henry Ford and Henry Miller.
 Numerous celebs have chosen Henry for their sons, from Julia Roberts to Minnie Driver to Heidi Klum to Colin Farrell.
 Appealing international versions include Arrigo, Enrico, Enzio and Enrique.

Henry

Jonathan was derived from the Hebrew name Yehonatan, eventually contracted to the modern Yonatan, meaning "gift of Jehovah." It comes from the elements yeho, in reference to God, and natan, meaning "to give." In the Old Testament, Jonathan was the valiant eldest son of King Saul, and it was his friendship with brother-in-law David that gave rise to the expression "Jonathan and David" to describe devoted, steadfast friends.
 
Jonathan is the biblical name that started to replace the stalwart John in the late fifties, sounding more playful, sensitive and modern. Now, after being high on the list for several decades, Jonathan has pretty much lost its luster.
 
Anne Hathaway named her oldest son Jonathan Rosebanks in 2016.
 
Jonathan has spawned numerous spelling variations, including Johnathan, Jonathon, and Jonothan.

Jonathan

Joseph is one of the most classic names in American nomenclature, popular with parents from many ethnic backgrounds and having dual-religious appeal.

The warm and friendly nickname Joe is the all-time regular guy name, as in Joe Blow, G.I. Joe, etc., celebrated in songs like 'Happiness is Just a Thing Called Joe.' Joe is frequently used on its own, as Kate Winslet did for her son.

Joseph evolved from the Hebrew name Yosef, which was derived from the verb yasaf, meaning "to increase." In the Old Testament, Joseph is the 11th and favorite son of Jacob and Rachel; in the New Testament, it is the name of the carpenter husband of the Virgin Mary, mother of Christ. 
 
Along with Joe, Joey is a usual short form. Variations of Joseph are popular worldwide, including Jose, Giuseppe and Josef, The most popular feminine form of Joseph is Josephine, but Joanna and Joanne are also found today for girls, along with Josie and Jo.

Joseph

Lars is a perfect candidate for a cross-cultural passport: it has been heard often enough here to sound familiar and friendly, yet retains the charisma of a charming foreigner.
 In this country Lars has been particularly associated with two Danes--Metallica's Lars Ulrich and film director Lars von Trier. In the 2007 movie Lars and the Real Girl, protagonist Lars Lindstrom was played by Ryan Gosling.

Lars

Leander was once an almost unknown name, however, with the popularity of Leo and the rise of Leandro, it now feels like a perfectly accessible alternative to Leon or Alexander. In Greek legend, Leander was the powerful figure who swam across the Hellespont every night to visit his beloved Hero, a priestess of Venus.
 Combining the Latin words Leo and Andros, this name has a cool, animal-related meaning, that lends it strength and bravery. A once familiar name in the US, it fell out of favor back in the 40s, though in the last decade, it has nearly doubled in use with almost 120 babies receiving the name in 2023.
 
While Leander is in the Norwegian Top 100 and the Nameberry Top 200, elsewhere, the Spanish variant Leandro or the French Leandre tend to be favored.

Leander

Can Linus lose its metaphorical security blanket and move from the Peanuts page onto the birth certificate? We think it has enough charm and other positive elements going for it for the answer to be yes.
 In Greek myth, Linus is both a musician and poet, the inventor of rhythm and melody who taught music to Hercules. In the Christian era, Linus was the name of the second pope, Saint Peter's successor, while in modern times chemist Linus Pauling was awarded the Nobel Prize twice.
 Humphrey Bogart as Linus Larrabee won the heart of Audrey Hepburn in Sabrina, and Matt Damon played Linus Caldwell in three of the Oceans movies. 
 Linus is currently in or around the Top 50 in Germany, Sweden and Norway, and is one of the most popular boys' names on Nameberry.

Linus

Kate and William shocked the world when they announced that they'd named their third child Louis -- Prince Louis Arthur Charles, to be more precise. But we've been predicting a comeback for this classic name for a long time. Both Louis and Lewis are already quite popular again in Britain. And several other high-profile parents —like actors Sandra Bullock and Bill Pullman— beat the Duke and Duchess to the punch by naming their sons Louis years ago. While the pronunciation in Britain is normally the French LOO-ee, in the US the final S is often pronounced. To get around the pronunciation confusion, many parents especially In the UK, go with the forms Louie or Lewis, with Louie ranking even higher than Louis. Lewis is in the Scottish Top 10.

Louis

The related Lucas and Luke are both hugely popular boy names in the US and internationally, and now Luca has joined them on boys' popularity lists around the world.

That's an astonishing success story for a name that was virtually unknown a generation ago. Only 13 baby boys were named Luca in the US in 1980, and by 1990 it was still only 32. But by the turn of the century, Luca took off and has now surpassed his more familiar brother Luke in the US.

Boy names ending in vowel sounds may have felt too feminine to early generations who lived by more conventional gender rules. And that old school he-man America also may have rejected names like Luca for being too "foreign". But in this era of Noah and Mateo, Elijah and Ezra, Luca has finally found widespread acceptance.
Along with its popularity in the US, Luca ranks highly in a range of countries that speak English, Spanish, French, and German, among others. While Luca is technically related to Luke and Lucas and so takes their ancient Roman habitational meaning, you might also see it as a relative of Lucius or Lucian, meaning light.
 Colin Firth and his Italian wife chose Luca for one of their sons, as did Hilary Duff, Vincent d'Onofrio, Rebecca Minkoff, and Jacinda Barrett and Gabriel Macht.

Luca

Luke is a cool-yet-strong Biblical name with a relaxed cowboy feel, which has been on the rise since the advent of Luke Skywalker.
 
Today, the Luke constellation of names is more popular than ever, with the ascendance of Top 10 Lucas and international star Luca. Luke ranks third in the group, but still stands in the US Top 50 and the Top 100 throughout the English-speaking world.
 
Luke originated as a short form of Lucas, a Latin derivation of the Greek name Loukas. The most famous bearer of the name is the first-century Greek physician—an evangelist and friend of Saint Paul, as well as the author of the third Gospel of the New Testament—who was also supposed to have been a portrait painter. He thus became the patron saint of doctors and artists.
 
Later Lukes have included Luke Duke of The Dukes of Hazzard, Cool Hand Luke, half of the classic soap opera duo of Luke and Laura, contemporary actors Luke Wilson and Luke Perry, and a number of star athletes.
 While Luke, Lucas, Luca, and the French Luc all have the same root and meaning, Lucius and Lucian have a different origin and meaning -- the more evocative "light".

Luke

Marius, frequently heard in Germany and France, is a slightly fusty yet accessible name that has (Les Mis) to Anne Rice. With the rise in interest in such Latin names as Maximus and Atticus, Marius might start attracting more attention.
Mario, the Italian, Spanish and Portuguese version of Marius, is much more widely used.

Marius

This attractively energetic Italian version of the classic Matthew is primed to move further and further into mainstream American nomenclature. Mateo is technically the Spanish version, but many parents in the US use the two spellings interchangeably. 
 
In the US, about 12,000 baby boys were named Mateo, Matteo, or Teo in 2021, vaulting the name in all versions into the Top 10. Mateo alone, by far the most popular version, lies just outside the Top 10.
 Actor Colin Firth has a son called Matteo, as does Ricky Martin; the Benjamin Bratts and Tom Colicchios have boys named Mateo. We're sure that both these spellings will keep climbing in tandem, sharing the possibility of the lively nickname Teo.

Matteo

Matteus

Milo is most commonly considered to be Germanic name derived from the Latin word miles, meaning "soldier." However, there is evidence to suggest it also may have independently spawned from the Slavic root milu, meaning "merciful." Milo predates brother name Miles, a variation that evolved when the name immigrated to the British Isles in the Middle Ages. Mylo is an alternate spelling.
 
Milo has long been a favorite <a href="https://nameberry.com/boys-names">boys' name</a> on Nameberry, also getting some well-deserved appreciation in the wider world. Milo combines the strength of the ancient Greek Olympic wrestler of that name—a six-time winner of the Olympic games—with the debonair charm of a WWII RAF pilot.
 More recently, Milo has been associated with the dashing Milo Ventimiglia of This Is Us fame, and it has also been the name of characters in books Catch-22 and The Phantom Tollbooth, and on screen in Milo and Otis, Alias, and Atlantis: The Lost Empire.
 Ricki Lake, Camryn Manheim, Sherry Stringfield, Liv Tyler, Craig Ferguson, and Alyssa Milano are six celebrity parents who share our enthusiasm for Milo, as do many Nameberry baby namers.
 Milo is often heard in Ireland. Milo O'Shea was a renowned Irish character actor.

Milo

Other kids might see a teasible connection to mortician or mortuary. Mortimer is an English family name used a few generations ago as an Anglicization of Moses; it was Walt Disney's original choice for the name of his mouse, until his wife talked him out of it.

Mortimer

Oliver is an international star, ranking near the top of the charts in the US and throughout the English-speaking world, along with a host of European and Latin American countries, from Norway to Chile, Slovenia to Switzerland.
 
Long a popular choice in England, Australia and New Zealand, Oliver entered the list of Top 100 <a href="https://nameberry.com/boys-names">baby boy names</a> in the U.S. for the first time in 2009, but has already jumped to the top of the charts. Why? Because Oliver is energetic and good-natured, stylish but classic, with a meaning symbolizing peace and fruitfulness. 
 
Oliver derives from Olivier, the Norman French variation of the Ancient Germanic name Alfihar ("elf army") or the Old Norse Áleifr ("ancestor's relic"), from which comes Olaf. Olivier emerged as the dominant spelling for its associations with the Latin word oliva, meaning "olive tree."

Oliver was used as a given name in medieval England after the spread of the French epic poem ‘La Chanson de Roland,’ which features a character named Olivier. It lost favor after the seventeenth century rule of Oliver Cromwell, then was revived in the nineteenth century. 

Oliver's biggest boost in this country came from the hit book and movie Love Story, which also catapulted the name Jennifer to stardom. Notable namesakes range from Oliver Wendell Holmes to Oliver Hardy to Oliver Stone. In fiction, there is Oliver Twist, and Oliver is also a Harry Potter name.
 Oliver works particularly well with single-syllable surnames, as in Oliver Stone, North and Puck (son of Wolfgang). Other celebrities who have chosen Oliver include Bridget Fonda, Fred Savage, Stephen Stills, and Taylor Hawkes. 
 International forms include the French Olivier, the Spanish Olivero, and the Italian Oliviero.
 Parents considering Oliver for their sons might consider that with Olivia at the top of the charts for girls, there will be an awful lot of children with names starting with Oliv-.

Oliver

Otis has real appeal for parents attracted to its catchy O initial and combination of strength and spunk. The appealing hero of the British TV show Sex Education has done much to propel Otis into the forefront of cool names.
 Otis originally came into use as a tribute to the Revolutionary hero James Otis, and would be familiar to kids via the Disney film The Adventures of Milo and Otis. 
 Though well used at the turn of the last century, Otis was off the charts for two decades from 1995 to 2014, and now sounds like a fresh choice. Tobey Maguire used the name back in 2009. More recently, and possibly contributing to Otis's return to the Top 1000 in 2015, Olivia Wilde and Jason Sudeikis gave the name to their son.

Otis

Raphael is a romantic archangel name that sounds both artistic and powerful. Raphael is also a great cross-cultural choice, with significance for people with both Latinate and Jewish roots, plus plenty of grounding in the English-speaking world.
 Raphael was one of the seven archangels (called by Milton "the affable archangel") who attended the throne of God and, as the angel of healing, is the patron of doctors as well as of travelers, science and healing. Another worthy namesake is the great Renaissance painter Raphael (born Raffaello Sanzio). Several celebs have chosen the name, including Robert De Niro, Ana Ortiz and Melissa George.
Rafael is the Spanish spelling, as represented by Spanish tennis champ Rafael Nadal. Rafi is the familiar Hebrew nickname.

Raphael

Remus is one of the legendary twins who, with brother Romulus, founded Rome.  An unusual yet classic name for the extremely adventurous who can put aside the stereotyped image of Uncle Remus.  Though because of that "ream" first syllable, we prefer Romulus.

Remus

Robert was the Number 1 boys' name in the US in both 1925 and 1950, and in fact was in the Top 25 for more than a century, giving it true classic status. Strong if not quite stylish, Robert remains in the Top 100 for baby boys as a family favorite.
 
Robert was derived from the ancient Germanic name Hrodebert, from the elements hrod, meaning "fame" and bertha, "bright." Robert was the name of three kings of Scotland, including Robert the Bruce, who freed Scotland from English rule. The name was brought to England by the Normans.
 Nicknames Bob and Bobby are stuck in the past, while Rob, Robb and Robby/Robbie have an ever so slightly more modern appeal. Antiquated pet forms Dob, Hob, Rab and Rabbie might be fresh nicknames, but the most fashionable form of Robert today is....Robert.
 There are countless literary and real-life namesakes, from poets Frost and Burns to actors Redford and De Niro to Shark Tank businessperson Robert Herjavec. Modern parents might consider honoring an ancestral Robert by choosing Robertson or Robinson, or even the derivative Robin, rising in popularity for boys.

Robert

Sebastian is an ancient martyr's name turned literary, and Little Mermaid hero—think Sebastian the Crab—that's more popular than ever, as a classic-yet-unconventional compatriot for fellow British favorites T Theodore and Oliver.
 Sebastian is derived from the Greek Sebastianos, meaning "from Sebastia." Sebastia was a city in Asia Minor—modern day Sivas, Turkey. Sebastian is a name with a substantial history, first as the third-century martyr whose sufferings were a favorite subject of medieval artists, then as the name of memorable characters in such varied works as Shakespeare's Twelfth Night and The Tempest and Evelyn Waugh's Brideshead Revisited.
 Sebastian is high on the lists in countries as widespread as Austria, Denmark, Romania, Australia and Chile. Some more down-to-earth nicknames for the relatively elaborate Sebastian not often heard in this country are Seb, Baz and Bas. 
Several celebs have chosen the sophisticated Sebastian for their sons, including James Spader, Kim Fields, Malin Akerman and Tommy Hilfiger.

As unlikely as it may seem, Theodore is a hot new hit name, vaulting into the Top 10 in 2021 for the first time ever and rising three more points last year to rank at Number 7.

Friendly nickname Theo may be responsible for some of that, though there are plenty of baby boys given Theo as their full name too. Add their numbers together along with those for Mateo and Teo, and they hands-down become the Number 1 boys' name.

Theodore and Mateo are far from interchangeable names, for sure, and some Theodores are called Teddy....or Theodore. But we predict an overwhelming number of little boys called Theo or Teo on American playgrounds over the coming years.

Theodore is a derivative of the Latin Theodorus, a variation of the Greek name Theodōros. The components are from the Greek words theos, meaning "God," and dōron, meaning "gift," giving Theodore the meaning "God-given" or "gift of God." Names with similar origins include Theodora, Dorothy, and Dorothea.
 
When Theodore Roosevelt took office in 1901, the name Theodore was in the Top 40 <a href="https://nameberry.com/boys-names">boy names</a>, with Teds and Teddys everywhere. After some damaging stereotypes—the chubby Chipmunk Theodore and Beaver Cleaver's real name—Theodore went into a decline, from which it has definitely made a recovery, thanks in part to the popular and likable nickname Theo.
 Theodore has been the choice of several celebrities, including Ivanka Trump, Bryce Dallas Howard, Natascha McElhone, and Ali Larter, not to mention being the fictional son of Christian and Ana in Fifty Shades of Grey.
 The name has a distinguished history. In addition to being presidential, it was borne by novelist Dreiser, poet Roethke, and French painter Gericault, and it was the first name (spelled Theodor) of Dr. Seuss.
 Among the well-known Teds, baseball's Williams and musician Nugent were born Theodore, but Ted Turner was christened Robert, and Ted Kennedy and Ted Danson were originally Edward.
 The beloved character Laurie in Little Women was named Theodore Laurence.

Victor is one of the earliest Christian names, borne (as Vittorio) by several saints and popes, symbolizing Christ's victory over death. It has been quietly in the Top 200 since 1880, but just recently has taken on a cool edge by fashionable parents in London and seems ripe for a similar reevaluation here too. 
 Victor made it big in the English-speaking world during the reign of Queen Victoria, one of the few <a href="https://nameberry.com/boys-names">boys’ names</a> popularized by a female version.
 Victor was the first name of Dr. Frankenstein, the scholar who brings the monster to life, and the romantic figure of Victor Laszlo in Casablanca, not to mention the esteemed writer Victor Hugo.
 Victor is currently popular in Denmark, Belgium and Spain. The Italian version Vittorio adds a large measure of charm.

Vincent is a name with a complex image. After being quietly used for centuries, it is suddenly seeming stylish, along wih other V names. Even the nickname Vince has been given a reprieve via actor Vince Vaughn and country singer Vince Gill. Vin Diesel was born with the more prosaic name Mark Vincent.
 Vincent was popular during the Middle Ages, especially among the French, who brought it to England. There are a number of St. Vincents, most famous of whom is St. Vincent de Paul, a seventeenth century French priest who organized societies of laymen to help the poor.
 Vincent has always been a favorite of Roman Catholic families, particularly in the Italian community. Its most notable bearer was Vincent van Gogh, but there also was philanthropist Vincent Astor, who gave it a patrician edge, and actors Vincent Price and Vincent D'Onofrio.
 Vincent/Vince/Vinny has appeared on screen as the central characters of My Cousin Vinny and Entourage. John Travolta had two key Vin-roles: Vinnie Barbarino in the TV series that launched him (Welcome Back, Kotter), and as Vincent Vega in Pulp Fiction. Vincent was the gentle giant on TV's Beauty and the Beast, and Ethan Hawke played a Vincent in Gattaca.

Wilfred is one of those Old Man Names that still sounds fusty in the US but is fashionable in the UK. It comes with readymade short forms Will or Fred and might make an adventurous alternative to the ubiquitous William. The central character of Walter Scott's Ivanhoe is the knight Wilfred of Ivanhoe. Wilfred Owens was a well-known British poet.

Chef Wolfgang Puck has helped soften this thunderous Germanic name; music-lovers will appreciate its association with Mozart, though the composer's middle name Amadeus is more appealing.
