Aaron is a name of subtle contrasts: an unusual spelling that is easily recognizable; a solid Biblical choice that doesn’t feel exclusively tied to religion; a well-established name for boys but sometimes confused with the girls’ name, Erin; used internationally but with notably different pronunciations; classic like Andrew but not out of place with recent favorites like Weston or Jayden. 
All things considered, Aaron’s enduring popularity feels at once surprising and obvious. And endure it does. For the last 50 years, it has been a staple in the US Top 100, and it remains a solid favorite in a number of European countries, from France to Switzerland. 
The origins of the name are debated, with some saying from Ancient Egypt, and has the meaning “warrior lion”, while others believe it is derived from Hebrew, with meanings such as “high mountain” or “exalted”. 
In the Old Testament, Aaron is a powerful figure, acting as a spokesman for his brother, Moses. He produced miracles and plagues to intimidate the pharaoh for enslaving the Israelites, and he was appointed by God as the first high priest. 
Other notable namesakes include the American politician, Aaron Burr, the composer, Aaron Copeland, and actors Aaron Ekhart, Aaron Taylor-Johnson, and Aaron Paul. The name has literary credentials too, with Shakespeare, John Steinbeck, and George Eliot using it in their works. 
Given to more than 4500 babies in the US every year, the soft sound of Aaron’s double vowels continues to hold an appealing gentleness for parents today. 
But why does Aaron have that unusual beginning and why is it pronounced differently across the world? 
Well, the original Hebrew name is Aharon, pronounced with 3 syllables, however, this sound had no equivalent in Greek. When Jewish scriptures were translated then, it was recorded as “Aaron”. While the Romans and Greeks might still have said “a-ha-ron”, it was later Anglicized in the 17th century to “air-un”. 
In England however, it is often said as “a-run”, where “a” is like the first sound of “apple”. This is likely down to people confusing it with the English name “Aron”, or because they were influenced by the Scottish Isle of Arran and the Irish Aran Islands. 
More broadly, pronunciation varies when Aaron is translated into the many languages used around the world. In German, it is A-rawn, while in Finnish, it is AH-rone or Aaro. In Arabic, Urdu and Turkish, it becomes Harun or Haroon and across Africa, it might be Haruna or Haron. 
Love Aaron but slightly put off by its widespread popularity? You could try Alden, Ansel, Taran, Canaan, Ariel or Abram.

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

One of the most evenly divided unisex names these days; strong and energetic, if overused, for both genders. 

Alex

The sweetest and most sensitive of the pet names for Elizabeth, now also one of the most dated. 

Beth

The unisex Blake, which indeed has two conflicting meanings, has a briskly efficient image when used for a girl. 
 Though in the eighties it was seen very much as a <a href="https://nameberry.com/boys-names">boys’ name</a>, epitomized by the character of Blake Carrington, the silver-haired, powerful patriarch of the TV soap Dynasty, these days it's more apt to be associated with Blake Lively, the attractive lead of the Gossip Girl series and the film Sisterhood of the Traveling Pants.

Blake

Carlos is the Spanish and Portuguese variation of Charles, which has been used in solid numbers in the US for as long as data has been kept. Carlos has never fallen out of the Top 600, but peaked from the 70s-early 2000s. Today Carlos is still within the Top 200. 

Notable namesakes include musician Santana, writers Fuentes and Castaneda, and numerous athletes. Carlos Irwin Estevez is the birth name of Charlie Sheen.

Carlos

The phonetic Carolyn spelling, which was very popular from the 1920s to the '60s, has been steadily on the wane while Caroline herself has stayed strong. 
 Carolyn Keene was the pseudonymous author of the Nancy Drew Books; Carolyn Jones played Morticia Addams on TV's The Addams Family.

Carolyn

Chris is a long-running nickname used almost equally for boys and girls.  While past its prime, Chris stands out as sounding completely appropriate for both sexes, perhaps because of its widespread use as a short form of both the popular Christopher and Christine.  Chris manages to retain its crisp appeal even though its fashion moment is over.

Chris

Darrell and all its variations was a trendy name in the 1950s and 1960s, an update on David and Daniel that began to fall out of favor by the 1970s and fell out of the Top 1000 completely at the turn of this century.

The Daryl spelling is most closely identified with actress Daryl Hannah, making this a unisex choice in theory, though last year about 75 baby boys were named Daryl....and no baby girls.

Daryl

David is an enduring worldwide classic, used from ancient times to the present day.
 David is derived from the Hebrew name Dawid, believed to come from the root dôwd, meaning “beloved”. The first famous David was the Old Testament second king of Israel: the shepherd boy who killed the giant Goliath, and later a warrior, poet, and powerful leader, wise but humanly fallible. He is an important figure in Judaism, Islam and Christianity, and later inspired many works of art, including Michelangelo’s colossal sculpture.
 Since then, there have been countless Davids of note in history, literature, and popular culture, including the patron saint of Wales — a translation of the Welsh name Dewi — two kings of Scotland. Then there’s Copperfield, Crockett, Bowie, Beckham, Letterman, Grohl, and many more. Celebrities who have chosen it for their sons include Jennifer Hudson, Bar Refaeli, and J.K. Rowling.
 In its international forms, David is steadily popular around the world, and ranks in the Top 10 names in Brazil, Austria, Armenia, Croatia, Bosnia and Herzegovina, and Israel.
 In the USA, David has never been out of the Top 40 boy names, but was at peak popularity in the mid-twentieth century, ranking in the Top 10 from 1936-1992. This means that, although it’s still given to thousands of boys each year, it has an “older man” feel to it. It ranks highest in states with a large Jewish population, and is still a Top 10 name in New York.
 After Daniel, David is the second most popular <a href="https://nameberry.com/search/boys-names/d">boy name starting with D</a>. Although fading a little in popularity, it remains a serious-yet-friendly classic with deep roots.
 If you’re looking to update David, perhaps as an honor name, the freshest alternatives are surnames deriving from David, including Dawes, Dawson, and Davies. You could also try an international variation, like Welsh Dai or Finnish Taavi.

David

Derek started out as a sophisticated Brit, but the name became so common over the last decades of the twentieth century that it lost much of its English accent, along with its stylish edge. Derek was a Top 100 name in the U.S. for 25 years, from 1970 to 1995.
 Derek was introduced into Britain during the Middle Ages by immigrant Flemish weavers.
Baseball star Derek Jeter spawned a whole new generation of namesakes.

Derek

Diana, the tragic British princess, inspired many fashions, but strangely, not one for her name. For us, Diana is a gorgeous and still-underused choice.
 Diana is the Latin name for the Roman goddess associated with the moon, virginity, and hunting; she is the protector of wild animals, represented in myth as both beautiful and chaste.
 Two of her most prominent bearers today are singers Diana (born Diane) Ross and Krall. Fictional Dianas appear in All's Well That Ends Well, Jane Eyre, and Anne of Green Gables.
 Now that the Duke and Duchess of Cambridge have named their daughter Charlotte Elizabeth Diana, perhaps this name will finally attract more attention and greater use.

Diana

Doug

Combine the charming heroine of the movie Legally Blonde with supermodel Elle Macpherson and the trend toward all names beginning with "el"—Ellie, Ella, Eleanor—and you have one hit name.
 Elle Driver is the Darryl Hannah character in Kill Bill, Elle Bishop was Kristen Bell's in Heroes, and Elle Fanning (born Mary, sister of Dakota) is a rising young actress.

Elle

Emily may have dropped somewhat in the current standings, but it was the most popular <a href="https://nameberry.com/girls-names">girls' name</a> for over a decade because it appeals on many levels: Emily is feminine, classic, simple, pretty, and strong. Emily is Number 1 among <a href="https://nameberry.com/blog/gen-z-names">Gen Z names</a>. It also has those nice literary namesakes, like Emily Dickinson and Emily Brontë.
 
Parents who a decade ago might have chosen Emily have moved on to Emma and now are looking at such alternatives as Amelia and Emmeline. But those girls' names, like Emma, may soon feel overused too.
 
Emily was derived from the Roman name Aemilia, which may have evolved from the Latin word aemulus, meaning "hardworking" or "rival." Emilia has the same Latin root as Emily, but Amelia has separate origins — it was derived from the Germanic name Amalia, meaning work. Emma is also rooted in German and means universal.
 
Modern Emilys in the spotlight include a number of the hottest young actresses — Emily Blunt, Emily Mortimer, Emily Deschanel — and even Emma Stone was christened Emily. And Emily is still one of the most widely used <a href="https://nameberry.com/search/girls-names/e">girl names starting with E</a>, on its way to overtaking A as the most fashionable first initial.

Emily

First-wave Irish name and place name—the poetic name for Ireland—now supplanted by newer alternatives such as Maeve and Delaney. 

Erin

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

This evocative Spanish surname would make an unusual but lively choice for a girl. 

Garcia

Gideon is a no-longer neglected Old Testament name, but still makes an excellent choice for parents looking to move beyond such overused biblicals as Benjamin and Jacob. In the Old Testament, Gideon was a judge called on by God to rescue the Jews from the Midianites, and the name was popular among the Puritans.
 Gideon was given a spike by the short-lived TV series Gideon's Crossing, and has been heard more recently as a main character in Criminal Minds, as Molly Weasley's brother Gideon Prewett in the Harry Potter series, and as an anti-hero, Gideon Gordon Graves, in the Scott Pilgrim series.
 The ubiquitous, in-every-hotel-room Gideon bibles were named because Gideon symbolizes great work done by few people.
 Among the celebs who have chosen Gideon for their sons are Neil Patrick Harris and Ziggy Marley.

Gideon

The second most popular spelling of this name is also the most straightforward. 

Haley

Hank is a midcentury guy nickname (which actually dates back to the seventeenth century) of the Al/Hal/Dick school, which has been on recess from the playground for decades. Now it's just beginning to be given on its own again, appreciated for its earthy, sportsguy cool. Hanks Aaron and Greenberg (born Henry) and Hank Williams (born Hiram) Sr and Jr. are worthy namesakes. 
 Kendra Wilkinson named her little boy Hank IV.

Hank

A newly successful name for girls, which, like Brayden and Caden, used to be strictly for the boys. Young Heroes and now Nashville star Hayden Panettiere planted it in the girls' camp.

Hayden

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

Jack may have fallen from its Number 1 place in England, but in the US it's as popular as it was at its height in the 1920s and 1930s. A durable, cheery, everyman form of John, Jack ranks as one of the most popular <a href="https://nameberry.com/search/boys-names/j">boy names starting with J</a>. 
Jack is a derivative of John that originated in medieval England. The name went from John to Johnkin to Jankin to Jackin to Jack. The name was so common in the Middle Ages that Jack became a generic term for a man. 
 
Jack is familiar to all from earliest childhood via Jack and Jill, Jack Sprat, Jack and the Beanstalk and Little Jack Horner et al. It is still a recent favorite for novel, TV and movie characters. 
 
Jack is at the top of the charts in Ireland and Scotland, and also ranks highly in Germany, Sweden, the Netherlands, and Belgium.
 
The jaunty Scottish version is Jock.

Jack

Jason, the Number 3 name for the entire decade of the 1970s -- thus the title of our original baby-naming book, Beyond Jennifer & Jason -- is more likely to be dad's name now than baby's, but it's still a widely used name. 
 
Jason's megapopularity definitely launched stylish newcomers ranging from Jacob to Mason to Jackson. It's easy to forget, given its trendiness, that Jason is actually one of the classic <a href="https://nameberry.com/baby-names/508/greek-names-for-boys">Greek names for boys</a>.
 In Greek myth, Jason is the leader of the Argonauts who went in search of the Golden Fleece, while in the Bible he was an early Christian who was hospitable to St. Paul.
Jason figures in the novels of William Faulkner, especially in The Sound and the Fury. Famous Jasons include Jason Bateman, Jason Segal, and Jason Kidd.

Jason

Jennifer is the Cornish variation of Guinevere, which ultimately derived from the Welsh name Gwenhwyfar. It has been in use in the English-speaking world since the 18th century but came to prominence in the 20th. Playwright George Bernard Shaw chose Jennifer for the name of his leading lady in his play The Doctor’s Dilemma, which drew more attention to the name.
 
Jennifer was the top name of the 1970s, when there were close to 800,000 Jennifers born: No wonder there are now online support groups for grown-up Jens who have suffered a lack of personal identity. These days Jennifer has fallen out of the Top 100 though it's forever a pretty-sounding name. 
 
Many modern parents opt for Jenna over Jennifer, though Jenna too is losing steam. Jenny and Jennie are forever appealing if not exactly stylish short forms; Jenifer is an alternate spelling.
 
One name that's taking over where Jennifer left off is Genevieve. Another idea for Jennifer lovers in search of an alternative: the perennially appealing Jane. Or even the original Welsh Guinevere.
 
Bill and Melinda Gates are the parents of a Jennifer. Wonder how she feels with a sister named Phoebe and a brother called Rory?

Jennifer

Joe is still the ultimate good-guy name, not at all diminished by its longevity or popularity or its everyman rep as Regular Joe, Cowboy Joe, G.I. Joe, Joe Exotic, Joe Blow, Joe Millionaire, Average Joe — and now President Joe (Biden). 
 There are millions of Josephs who have gone primarily by the nickname Joe; just a few of the more prominent Joes are Biden, Namath, Torre, Di Maggio, Lieberman, Montana, and Jonas.
 Several celebrities have chosen Joe as a full name for their sons, including Kate Winslet, Kevin Costner, Sting, and Stephen King.
 While Joe and long-form Joseph have always been among the most common male names in the US, there was never a President Joe until Biden.

Originally used for children baptized in holy water from the river Jordan, it became one of the leading <a href="https://nameberry.com/unisex-names"> androgynous names</a> of the nineties. As the balance tips toward the boys' side, it's slipping on the girls' popularity chart. Alternate spelling Jordyn is now more popular for girls.

Jordan

Joy is from an older generation of word names, which also included Merry, Bliss, and Glory -- all of which exert a certain amount of personality pressure on a child. One interesting name that means the same thing: Chara.
 Joy began to be used as a name by the seventeenth century Puritans, with the idea of "being joyful in the Lord." It came into more general use in the late nineteenth central, part of the revival of virtue names. Her high point was in 1974, when she reached Number 109 on the <a href="https://nameberry.com/popular-names">popular names</a> charts. Joy has also been often used as a middle name. Two recent bearers: comedian/TV personality Joy Behar and Joy Mangano, the inventor whose life was the basis of Oscar-nominated biopic Joy, starring Jennifer Lawrence.

Kai is an internationally flexible name with many possible origins and meanings, growing in popularity in the US and a diverse range of European countries.
 
In the US, the name Kai is most commonly referred to as being of Hawaiian derivation, meaning "sea." In Europe, Kai is largely considered to have Frisian origin as a diminutive of the name Kaimbe, meaning "warrior", or as a short form of Gerard "brave spear". 
 
Kai is also found as an independent name in African, Chinese, Turkish and Native American cultures. Kai is a strong, evocative multi-cultural name that packs a lot of power in its single syllable. 
 
Famous as the name of the boy enchanted by the fairy-tale Snow Queen, Kai was chosen for her son by actress Jennifer Connelly and as a middle name for son Samuel by Naomi Watts and Liev Schreiber. 
 
Kai is popular with Berries as both a first and middle name choice. Perhaps because of its international familiarity, Kai is popular in video games. Its most prominent namesake is Danish-born jazz trombonist Kai Winding.
 
Kai ranks in the US Top 1000 for girls, but is used more than 90 percent of the time for boys. Donald Trump, Jr. has a daughter named Kai Madison and Gigi Hadid and Zayn Malik named their daughter Khai in 2020.

Kevin came to the US with the large wave of Irish Immigrants after World War I, hitting the US Top 1000 list for the first time in 1921 and never leaving.
 Though an ancient Irish name -- a Saint Kevin founded a scholastic monastery near Dublin in the seventh century -- Kevin only became popular in Ireland at the same time it did in the US, when the Irish war for independence restored native Irish names to general use.
 
The name Kevin was derived from the name Caoimhín, which originated from the Irish elements coém, meaning "handsome," and gein, "birth." The feminine name Caiomhe, anglicized as Keeva, comes from the same origins. 
 
Kevin has been waning in popularity in the US in recent years—it dropped out of the Top 100 for the first time since the Truman administration in 2017—but remains a popular name in countries as diverse as Italy, Mexico, Sweden, and several Eastern European countries. It was the top boys' name in France in the early 1990s—one of the first non-French names to hold the title.
 
That said, Kevinism has become slang for fleeting name phenomena, typically associated with pop culture trends. Internationally, it's identified as a stereotypical trendy "American" name.
 
There are many famous Kevins in the public eye, notably Kevin Costner, Kevin Bacon, and Kevin James. Shark Tank's Kevin O'Leary, aka Mr. Wonderful, was born Terrence Thomas Kevin O'Leary and founded The Learning Company.

Kevin

Krystall

Lewis is the best spelling to choose if you want this pronounced with the S. Lewis has been in the Top 5 in Scotland since 2000, and is one that parents in the U.S. are just beginning to rethink.
 Lewis was a Top 100 name in this country from 1880 to 1930, reaching Number 30 in 1880. One of its most famous namesakes is Lewis Carroll, born Charles. A current bearer is comedian Lewis Black. Lewis is also a very common surname, as in Lewis & Clark, Jerry Lewis, Jerry Lee Lewis, Daniel Day-Lewis, Sinclair Lewis, Leona Lewis, and many other notables. Interesting fact: Louis Armstrong pronounced his first name as Lewis.
 Nickname/middle name Lou is making a comeback for girls (as in Keri Russell's Willa Lou), so why not Lew for boys?

Lewis

Linda will live forever in baby name history for toppling Mary from its four hundred year reign as Number 1. Queen of Names in 1947, Linda has fallen even further in favor than Mary today. 

Linda

Elvis naming his daughter Lisa Marie and Nat King Cole's hit song "Mona Lisa" conspired to catapult one of Elizabeth's many offshoots to a high of #4 in 1970. 

 It has largely fallen from favor in the English-speaking world since then, but still ranks highly in countries such as Austria, Belgium, Switzerland, France and the Netherlands. It has a sweet and simple charm that could be ripe for an early revival in the US too.

Lisa

A girl named Liz on her birth certificate could feel deprived of her full identity. Call her Liz, but name her Elizabeth -- or at least Lizbeth or Eliza.

Lou, all by itself, is become fashionable for girls, which usually makes a name LESS fashionable for boys.  But Lou, like Bill or Jim, is rarely used on its own for boys anyway.  (You wouldn't name a boy Frederick Lou the way that girls are named Mary Lou or, in the case of Keri Russell's new baby, Willa Lou.)  Long form Louis is getting cool again and, with the Lewis spelling, is the Number 2 name in Scotland.

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

Maeve is a short and sweet name that has become one of the most stylish Irish names for girls in the modern US. Maeve would make an excellent first or middle name choice, with more heft than Mae/May and more modern charm than Mavis. 
 Maeve appears in Irish mythology in two forms, one as the powerful Queen of Connacht, the other as the queen of the fairies. Maeve of Connacht was a warrior queen, famous for starting a war in attempt to steal her ex-husband’s stud bull. Other spellings are Meabh, Medb and Meadhbh, which are connected to mead, a honey-based wine that was produced in many ancient cultures.
 
Chris O'Donnell, Lili Taylor and Kathryn Erbe used Maeve for their daughters. The Irish author Maeve Binchy also is a well-known bearer. Maeve is the name of one of the lead characters on the HBO show Westworld.
 Irish spelling Meabh is popular in Ireland, but not recommended in the US.

Maeve

Mateo vaulted into the boys' Top 10 in 2023, ranking all the way up at Number 6. Counting Mateo and Teo along with Anglo equivalents Theodore and Theo make this by far the Number 1 boys' name in the US.
 
Mateo is one of the Latinate names that, like Mia and Luca, is becoming popular far beyond its native Spanish community.
 
The Spanish form of Matthew, which derived from the Hebrew name Mattiyahu, Mateo can also be spelled Matteo, technically the Italian variation. Mattiyahu consists of the elements mattan, meaning "gift" and yah, which references the Hebrew God. 
 
Mateo is enormously popular in Spain and Latin America, but it's also a top boys' name in the US along with several other countries in central and eastern Europe. Its approachable spelling and pronunciation for non-Spanish speakers is one reason it's found such widespread favor. Plus it's a fresh spin on dad name Matthew and a shortcut to the stylish short form Teo.

Actor Colin Firth has a son called Matteo, the Italian form; the Benjamin Bratts have a Mateo. 

Matheo is an archaic Spanish spelling, although it is used in France as Mathéo.

Mateo

Matthew was the third most popular boys' name in America throughout the 1980s and '90s, and is still one of the top <a href="https://nameberry.com/search/boys-names/m">boy names starting with M</a>. The New Testament Matthew is the epitome of the fashionable classic—safe and sturdy, yet with a more engaging personality than John or William.
 
Matthew is the English derivative of Matthaios, the Greek form of the Hebrew Mattiyahu, composed of mattan, meaning "gift" and yah, in reference to God. The biblical Matthew was the apostle who wrote the first Gospel in the New Testament. Mateo, Matthias, Teo, Matek, and Mattia are among the many names derived from Matthew.
 Matthew is so common by now, though, that parents have started to seek fresher choices, like Matthew-inspired variations Matthias and Mateo. 
 
The name suddenly became very popular in the U.S. in the 1960s, with Matts appearing on many Western (e.g., Gunsmoke's Marshall Matt Dillon) and other TV shows. Currently there are several prominent real-life Matthews and Matts, including Broderick, McConaughey, Lauer, Damon and Dillon. Celebs who have chosen international versions for their starbabies include Ricky Martin (Matteo), Benjamin Bratt (Matteo), Colin Firth (Mateo) and Will Ferrell (Mattias).

Matthew

Meg, perennially one of the Little Women, is a Margaret short form that manages to be neither quite in nor quite out of style. Meg is sleeker and more sophisticated than Maggie, more contemporary than Peg, more stylish than Megan, and still one of the best diminutives of Margaret. 
Meg Ryan was born Margaret Mary Emily Anne.

Michael was the Number 1 American boys' name for almost half a century. While Michael has moved out of the Top 10 <a href="https://nameberry.com/boys-names">baby boy names</a>, it's still widely used. 
 
How has Michael racked up this phenomenal record? Credit its use by parents of diverse ethnic and religious groups, and Michael's all-around likability, strength, and sincerity. 
 
Michael was derived from the name Mikha’el, which comes from the rhetorical question mī kā’ēl, meaning "who is like God?" in Hebrew. In the Bible, Michael is the archangel who led the other angels to victory in a war against Satan, one of only two archangels (the other is Gabriel) recognized by Jews, Christians and Muslims alike. 
 
Today, Michael may feel more like a dad name than a baby name. Substitutes you might consider include Micah, Malachi, Gabriel and Raphael.

Michael

This image of this distinguished Anglo-Scottish surname, drawn from the French place name of the ancient castle of Saint Foi de Montgomery, is rapidly shifting from fusty and formal to cool. And dashing short form Monty (or Monte) nudges it to cute. 
 Best-known bearer of the name is beautiful-but-tortured midcentury actor Montgomery Clift. Roger de Montgomery was a Norman nobleman who was made Earl of Arundel after he invaded England in 1066 and Sir Bernard Montgomery was a noted army commander in World War II. Montgomery is also the proper first name of Star Trek's engineer Scotty and, less flatteringly, the middle name of The Simpsons' evil Mr. Burns.

Montgomery

Penelope is an unlikely 21st century baby name success story. Off the Top 1000 for 25 years, Penelope jumped back on in 2001 and has been heading uphill ever since, propelled by the trend for mythological names, Spanish actress Penelope Cruz, and some high-profile celebrity babies. 
 
In Greek mythology, Penelope was the wife of Odysseus in Homer’s Odyssey. It has two possible origin stories—Penelope was either derived from the Greek pēnē, meaning "thread of a bobbin", or from penelops, a type of duck. Mythological Penelope was cared for by a duck as an infant, and later was known for fending off would-be suitors by pretending to weave a garment.
 
Penelope's status as a Kardashian baby name -- Kourtney's daughter Penelope was born in 2012 -- brought the ancient name to widespread attention. The most popular <a href="https://nameberry.com/search/girls-names/p">girls' name starting with P</a>, Penelope was also picked for their girls by Tina Fey, by Anna Chlumsky, and by Natalie and Taylor Hanson, of the group Hanson. 
 Penelope has several British novelists as namesakes—Penelopes Fitzgerald, Mortimer, Gilliatt, and Lively. And yes, she's also a Harry Potter character: Penelope "Penny" is a student at Hogwarts.
 A perennial Nameberry favorite, Penelope can be shortened to the traditional Penny or -- Berry style -- the fresher Nell or Poppy.

Penelope

Portia is a perfect role-model name, relating to Shakespeare's brilliant and spirited lawyer in The Merchant of Venice, and is now also a Hunger Games name . 
 Another Shakespearean Portia was the wife of Brutus in Julius Caesar, based on a historical character. In the 1940s, when the name was most used, there was a popular radio soap called Portia Faces Life, the heroine being – what else? – a brilliant and spirited lawyer.
 Portia is a recommended choice, even though some people might think you named your child for the car. Just don't spell it Porsche, which may sound the same but has a totally different and – despite the aspirational brand – less refined image.
 Namesake Portia de Rossi actually started life as Amanda/Mandy.

Portia

Prentiss

The Reid spelling is the most popular by half, probably because it feels more like a name than Reed, which looks more like a word. It's used occasionally for girls but this name is firmly in the boys' camp.

Reid

Spelling variations abound when a name is trendy, which Rosalind is not these days.  We say leave Roslyn back in the middle of the 20th century and reclaim the original Rosalind.

Roslyn

Roxy, also spelled Roxie, is one of those high-stepping showgal names with plenty of moxie, among the many sassy nickname names on the U.K. popularity list--currently Number 398.
 The fictional character Roxie Hart has had a long and interesting life, beginning with the 1926 play Chicago, then a silent film, a 1942 hit movie starring Ginger Rogers, a 1975 Broadway musical with Gwen Verdun as Roxie, plus the 2002 movie Chicago, with Renee Zellweger playing the part.
 Other Roxys have appeared on Hannah Montana and Sabrina the Teenage Witch.

Sam has long been used on its own for boys, as accepted standing by itself as it is as a short form of Samuel. Straightforward and down-to-earth, Sam is the name of the son of the co-stars of The Americans, Keri Russell and Matthew Rhys.

Sam is one of the most popular <a href="https://nameberry.com/search/baby-names-starting-with/s">names that start with S</a> in the Western world, ranking higher in several European countries than it does in the US, where it's trended downward since the 19th century, though it's always been in the Top 1000.

A place name with a deep Southern accent, the once-obscure Savannah shot to fame, with others of its genre, on the heels of the best seller Midnight in the Garden of Good and Evil, which was set in the mossy Georgia city of Savannah. Originally a substitute for the overused Samantha, Savannah is now becoming overused itself, long among the top <a href="https://nameberry.com/search/girls-names/s">girls' names starting with S</a>.
 Before that, there were Savannahs in the novel and movie The Prince of Tides, in the Terry McMillan hit novel and film Waiting to Exhale, played by Whitney Houston and, even earlier, in a 1982 movie called Savannah Smiles.
 Savannah has actually been on the popularity list since records started being kept in the 1880's; she's been in the Top 100 since 1993. Desperate Housewives' Marcia Cross chose Savannah for her twin daughter, and it's the name of Queen Elizabeth's first great-grandchild. And Savannah Guthrie can be seen every morning on the Today Show.

Sean, after a long reign as one of the top <a href="https://nameberry.com/list/328/irish-baby-names-for-boys">Irish boys' names</a> in the US, has now slipped as parents look to fresher Irish choices such as Liam and Aidan. In Ireland, Sean is still highly popular, but variation Senan, an Anglicized spelling of diminutive Seanan, is also stylish in Ireland. While Sean is the Irish form of John, Seanan and Senan may be thought of either as Sean diminutives or relatives of the Latin word "senator".

Widely heard in both Italian and Spanish households, Sergio and his many international brothers are rooted in Sergius, one of the original Roman family names. The meaning is unknown, but possibly is related to servant or protector.

Other variations of Sergius heard around the world include the French Serge and the Russian and Eastern European Sergei. There have been four Popes named Sergius along with several saints.

Sergio has been well-used in the US since right after the second World War and still ranks among the top half of the US Top 1000 boys' names. It's a Top 100 boys' name in Spain and is also popular in Mexico.

Spencer is a name that has everything: it's both distinguished sounding and accessible, dignified but Spencer Tracy-like friendly. Picked by several celebrities (a couple of times even for a girl), adding up to an enthusiastically recommended choice.
 As a family surname, Spencer became the middle name of Winston Churchill, and was the maiden name of Princess Diana. The surname version was often spelled Spenser in the past, as in Edmund Spenser, the poet known for The Faerie Queene.
 The protagonist of Henry James's short story The Jolly Corner" is Spencer Brydon.

William is one of the most enduring of classic names for boys. It's also among the most popular boys' names, as American parents see it as being ideally conservative yet contemporary, and hands-down the most popular <a href="https://nameberry.com/search/boys-names/w">baby name beginning with W</a> of all time. 
 For 400 years, William has been second only to John as the most popular name in the English-speaking world. And now of course, it's also a newsy name—thanks to Britain's high-profile Prince William.
 William is derived from the Germanic name Wilhelm, composed of the elements wil, "will," and helm, referring to a helmet or protection. The name was introduced to England by William the Conqueror, with William being the Norman variation of the name. In Central and Southern France, it was translated as Guillaume.
 
In terms of short forms, yesterday's Bills and Billys have given way to today's Wills—or Williams, with no diminutive—though a few hip Billys, including Helena Bonham Carter and Tim Burton's, have surfaced recently. 
 But Irish spinoff Liam is the most stylish William nickname and has now superseded William, becoming the most popular boy name in America. Riding the William bandwagon is the Dutch Willem, which comes with the unique nickname Pim.
 
William has long reigned as a royal name in the U.K. There are tons of worthy namesakes called William, including William Shakespeare, Bill Gates and four U.S. presidents.
