The ancient German name Adelheidis gave rise to both Adelaide and Adelheid. While Adelaide is more popular and better known internationally, Adelheid is still used occasionally in Germany, the Netherlands, and Scandinavia. The German pronunciation is not that different from Adelaide, with a soft h and a long I sound instead of a long A in the last syllable.

Heidi originated as a short form of Adelheid.

Adelheid

These days Albrecht is mostly seen as a surname, although it was historically a well-used first name in Germany. The surname was derived from the given name.
 
Notables Albrechts include Renaissance painter Albrecht Altdorfer and the fictional Albrecht from the ballet Giselle.

Alexander has been in a Top 25 boys' name in the US for 30 years now. But namers are still attracted to its imposing historic pedigree.
 Alexander is derived from the Greek name Aléxandros, composed of the elements aléxein, meaning "to defend," and aner, meaning "man." 
 
According to Greek legend, the first Alexander was Paris, who was given the nickname Alexander by the shepherds whose flocks he defended against robbers. He was followed by Alexander the Great, aka Alexander III, who conquered much of Asia.
 
A royal name in Scotland, Alexander is still highly popular there. In Gaelic, the name became Alasdair; in Spain, Alejandro; and in Italy, Alessandro.
 
The noble Alexander has led to the popularity of many spinoffs, such as Alex, Zander, Xan and Zan, along with female versions such as Alexandra, Alexis, and the unfortunate Alexa.
 Among the many notable Alexanders in history, standouts are Hamilton, Graham Bell, Fleming, Pope and Haig.
 Naomi Watts and Liev Schreiber's Alexander is known as Sasha.

Amalia is a widely cross-cultural name, heard from Italy to Romania, Germany to Scandinavia. The current heir to the Dutch throne is Princess Catharina-Amalia of Orange. It can be pronounced ah-MAH-lee-a or ah-mah-LEE-a. 
</br.
Like Amelia and Emilia, this name is likely to continue to climb. Frequently in the US Top 1000 in the early twentieth century, it spent nearly eighty years off the list until rejoining in 2011.
 Amalia's popularity was spread in eighteenth century Europe due to the fame of Anna Amalia, a Duchess who was a great patron of the arts.
 Amalia would make a lovely and more distinctive alternative to Amelia. Another spelling variation is Amalya.

Amalia

Anna has become the dominant form of the Ann family, offering a touch of the international to English speakers and a bit more style than the oversimplified Ann or Anne.
 Anna is the Latin form of Hannah, a Hebrew name that derived from root chanan, meaning "grace." European Christians embraced the name for its associations with the Virgin Mary’s mother, Saint Anna — known in English as Saint Anne.
Anna has been used for generations throughout Europe, from Russia to Italy, Spain to The Netherlands. While Hannah and Anna are the most common forms of the name, variations including Annie, Annalise, Anya, Anika, Nancy, and Anais also rank in the US Top 1000.
 
Classic and simple, Anna would be an excellent choice for parents in search of a name that will bridge two different cultures, say Jewish and Italian.
 
In literature, Anna is associated with Tolstoy's Anna Karenina. The name was given some fresh life when it was used for the adorable younger sister voiced by Kristen Bell in the animated film Frozen. Three current bearers are actresses Anna Kendrick, Anna Friel, and Anna Paquin.
 
Anya takes it more into international territory, and Anja, even further. Read more about Anna and other <a href="https://nameberry.com/blog/disney-princess-names">Disney Princess Names</a> in our featured blog.

Anton

Antonia is stronger than most feminized <a href="https://nameberry.com/boys-names">boys’ names</a>, reflecting the pioneer spirit of Willa Cather's classic novel My Antonia. Antonia is hovering near the bottom of the US popularity list, which may be an excellent reason for you to use it.
 Antonia was borne by several prominent women in ancient Rome, including the mother of the Emperor Claudius. A recent distinguished namesake is British historian/biographer Lady Antonia Fraser. It is also the full name of actress Nia Vardalos.

Antonia

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 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.

Barbara is back! Among the fastest-rising names of 2023, Barbara came back from oblivion at the very bottom of the Top 1000, gaining nearly 100 places on the popularity list.
 
Credit 2023's breakout movie Barbie, which gave a new stylish feel to the classic Barbara. Rooted in ancient Greek and ranking in the Top 10 in the US throughout the 1930s, 40s, and 50s, Barbara is now poised to become fashionable again for the next generation of babies.
 The name Barbara has the same root as the word barbarian, meaning stranger or foreigner. There is the popular third century St. Barbara, who was reputed to have been imprisoned in a tower and may have been the inspiration for Rapunzel. She became the patron of architects, stonemasons, fortifications, and geologists, and protects against fire and lightning.
 
Barbaras appear in works by Dickens and Thackeray and, most notably, as the idealistic protagonist of the George Bernard Shaw play Major Barbara. Noteworthy bearers include real estate mogul Barbara Corcoran, actress Barbara Stanwyck (born Ruby), novelist Barbara Pym, TV's Barbara Walters, and "My Name is Barbra" Streisand. Barbara Gordon was the original Batgirl in the comic books.
 And the of course there's Barbie, though today, Bebe, Bobbie, or even Babs might make a cuter retro nickname.

Barbara

Charlotte, the name of the young Princess of Cambridge, is the latest classic name to join Sophia, Emma, Olivia, and Isabella at the top of the popularity list. It is now among the most popular girl names in many English-speaking and European countries.
 
The feminine form of Charles, Charlotte derived from Charlot, a French diminutive of Charles meaning "little Charles" and the name of Charlemagne’s son in French literature and legend. The name was popularized by England's Queen Charlotte Sophia, wife of King George III.
 
Queen Charlotte was the mother of fifteen children and a patron of Mozart and Bach. She and George ruled England in the late eighteenth and early nineteenth century during the French and American revolutions.
 
Charlotte is an elegant royal name, with a host of widely varied role models, from Charlotte Brontë to the spidery protagonist of E. B. White's Charlotte's Web to the more recent Charlotte York, aka the prissy one, of Sex and the City. Charlotte is appealing to a wide range of parents because it sounds feminine yet grownup, sophisticated yet lush. 
 
Charlotte is a pop culture staple—it was Scarlett Johansson's character in Lost in Translation and has been featured on TV shows like Lost and Revenge. The band Good Charlotte was named for a children's book with that title. An all-around winner of a name, Charlotte has been chosen by Chelsea Clinton, Dylan McDermott, Colin Hanks, and Sarah Michelle Gellar and Freddie Prinze Jr.
 In addition to Charlie, Lottie makes a cute nickname.

Charlotte

Christina, a pretty and feminine, crystal clear classic, may be trending downward, but it's never out of style. Christina's short forms Chris, Christie, and Tina all seem dated—making the royal Christina best used in its full glory. 
 Christina became a royal name in Sweden (Greta Garbo played Queen Christina in one of her classic films) and Spain, and it is more usable today than the French Christine.
 Christina is now well represented by actresses Applegate, Ricci, and Mad Men's Hendricks, alongside singer Aguilera and Orphan Train novelist Baker Kline. Previous bearers include British poet Christina Rossetti and Australian novelist Christina Stead.
 Christiana is a more distinctive variation.

Christina

Christine was the dominant feminine variation of Christopher forty or fifty years ago, when French E-endings were preferred over As; it was a Top 20 name for several years, from 1966 to 1974. But though it still hangs in on the popularity list, today most any other version would be considered more stylish, from Kristen to Kirsten to Christina herself.
 Christine is the heroine of the 1910 novel and hit musical Phantom of the Opera and the automotive protagonist of Stephen King's 1983 horror novel. Christine has been serenaded in song by everyone from Elton John to Kiss to Motorhead.

Cacilia

Eleonore

This spelling of the classic name is found in France, Germany, Greece, and other cultures, and is worn by such notables as Elisabeth Kubler-Ross, Elisabeth Shue, Elisabeth Moss, and Elisabeth Hasselbeck. The name's pronunciation is usually just like the Z version, but some parents choose this because they want to discourage the Liz or Lizzie short forms and so pronounce it as if it has Lisa in the middle.
 Elisabeth is nicknamed Bethsy in the 2008 film adaptation of Thomas Mann's Buddenbrooks, Bep in The Diary of Anne Frank, and Betsy in the Wolverine universe.

Elisabeth

Concise and clipped European version of the earnest Ernest.

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

Ferdinand, a traditional name in the royal families of Spain and a handsome young prince shipwrecked on Prosper's island in Shakespeare's The Tempest has, unfortunately, to the American ear a somewhat heavy and clumsy feel – most likely because of the bull connection. In the 1880's it was in the 200's on the US pop list, but has been off completely since 1986. 

 The sleeker Spanish and Portuguese version Fernando, on the other hand, is Number 253 (and 28 in Chile, 59 in Spain). An interesting Dutch spin: the short form Dinand, after a popular singer.
Portuguese explorer Ferdinand Magellan was the first European to cross the Pacific and the first person to circumnavigate the earth.

Ferdinand

Franz is the German equivalent to Francis, and you'll be hard-pressed to find a Franz outside of countries with Germanic origins. In America the name is often associated with celebrated author Franz Kafka, who was born in Prague.

Franz

One of the most familiar <a href="https://nameberry.com/baby-names/160/german-names">German names</a>, with an upright Prussian image. Friedrich might just have been out for long enough to start coming back in.

Whether it's pronounced with an "een" or an "aine" or an "enn" sound at the end, Helene doesn't feel as current the more forthright Helen or the airier Helena. Helene reached a high of Number 228 in the US in 1916, when ene, ine and een names were all the fashion, and stayed in the Top 500 until 1962, making a final exit in 1970. It still ranks well in its native France, and even more in Norway (#70).  Model Heidi Klum's daughter 'Leni' has Helene on her birth certificate.

Helene

Isabella has been a Top 10 name for girls in the US for two decades now. The Latinate form of Isabel, a variation of Elizabeth which originally derived from the Hebrew name Elisheba, Isabella reigned as Number 1 in 2009 and 2010.
Isabella, which feels both modern and traditional, has incredible cross-cultural appeal to parents from a range of religious and ethnic backgrounds. It's feminine but also substantial, with a long history as a royal and classic name comfortable on the international stage. 
 
Isabella is of course wildly popular in both the English and Spanish speaking worlds, but it also ranks among the Top 100 girls' names in a wide range of western countries, including Germany, the Netherlands, and Scandinavia.
 
Isabella's success is due at least in part to the 'Twilight' effect and lead character Isabella 'Bella' Swan. Some parents choose it to get to the short form Bella, while others prefer to use the irreverent Izzy or Issy, while still others insist on using it in its full four-syllable glory.
 
Variations Isabelle and Isabel are also popular, with the Scottish spelling Isobel another possibility. Newer alternatives include Sabella and Isabetta.
 Isabella is familiar through various European queens, including the Queen of Spain who funded Christopher Columbus, and was used by Shakespeare in Measure for Measure.

Isabella

The traditional German spelling of this name, used by Goethe, Bach and many other luminaries.

Johann

Johanna is the version of this name used in Holland, Germany, and Scandinavia. The extra h makes Johanna a slightly more dignified version of Joanna. 
 A notable namesake is the author of Heidi, Johanna Spyri. There are Johannas in Sweeney Todd, The Hunger Games, and the Bob Dylan song, "Visions of Johanna."

Johanna

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

Josepha is less heard in this country than in other parts of the world, seen as a slightly awkward feminization a la Ricarda and Benjamina.  In the U.S., Josephine or Joanna is the more usual feminine form of Joseph, though you might consider Josepha if you want to break rank.

Josepha

Karl

Karolina

Karoline is the form of the classic Caroline commonly used in Germany and throughout Scandinavia, where it is popular. It's an acceptable if not tradition spelling variation, given to nearly 100 baby girls in the US last year, versus more than 3000 named Caroline.

Karoline

Katharina is an attractive form of Katherine and a great way to update a classic. But English speakers may want to choose the Katerina or Katarina spelling to avoid pronunciation confusion.

Katharina

Klementine

Kunigunde

This aristocratic, somewhat formal Germanic route to the popular Leo is a royal name: Queen Victoria used it to honor a favorite uncle, King Leopold of Belgium. Though Leopold sounds as if it might be a leonine name, it's not really a relative of such choices as Leon, and Leonard.
 In literature, the name is famous via Leopold Bloom, the central character of James Joyce's Ulysses and in music is associated with the distinguished conductor Leopold Stokowski, and it is also a saint's name.

Leopold

A sophisticated <a href="https://nameberry.com/girls-names">girls' name</a> for those attracted to Leona, Leonie and Leonore.

Magdalena is a pretty name forever associated with the fallen-yet-redeemed Mary Magdalen; often heard in the Hispanic community.  But forward thinking parents are reviving Magdalena along with Magdalene and the unrelated but similar-sounding Marguerite.

Magdalena

Margarethe

As a highly popular <a href="https://nameberry.com/girls-names">girls’ name</a> in all Spanish-speaking countries, this saintly Latin variation of Mary retains a timeless beauty. Through the centuries, Maria remains one of the most widely-used <a href="https://nameberry.com/search/girls-names/m">girl names starting with M</a>.
 This widespread name understandably has produced notable namesakes in almost every field – opera's Maria Callas (born Sophia Cecelia), tennis's Sharapova, education's Montessori, ad infinitum. And she's been celebrated in song as well, from Ave Maria to the eponymous song in West Side Story to "How Do You Solve a Problem Like Maria?" in The Sound of Music. 
While the usual English pronunciation these days is the same as it is in non-English-speaking countries – mah-REE-ah – the British used to pronounce it mah-RYE-ah, like Mariah Carey.

 Maria ultimately dervies from the Hebrew name Maryam/Mariam. The original meaning of Maryam is uncertain, but theories include "drop of the sea" (from Hebrew roots mar "drop" and yam "sea"); "bitter" (from Hebrew marah "bitterness"); and "beloved" (from the Egyptian root mr).

Maria

The ubiquitous French version of Mary came into the English-speaking world in the nineteenth century. In the United States, Marie was a huge hit at the turn of the last century and for the ensuing fifty years, becoming the seventh most popular name in the country for three years, from 1901 to 1904.
 Now, though, Marie sounds more dated than either Mary or Maria, though it once rivaled both. Even its days as a widely-used middle name have passed. The freshest way to use Marie today may be as the first part of a traditional French double name: Marie-Christine, Marie-Claude, and so on, or the French diminutive Manon.
 There have been countless notable Maries over the years, from French Queen Marie Antoinette to physicist Marie Curie to singer Marie Osmond (born Olive Marie).
 Marie is the French form of Maria, which ultimately was derived from the Hebrew name Maryam/Mariam. The original meaning of Maryam is uncertain, but theories include "drop of the sea" (from Hebrew roots mar "drop" and yam "sea"); "bitter" (from Hebrew marah "bitterness"); and "beloved" (from the Egyptian root mr).

Marie

With Matthew sounding somewhat exhausted, and ancient endings sounding new again, this New Testament apostolic name makes an appealing and recommended choice. Both Mathias and Matias are well used in the Hispanic community, and throughout Europe. Will Ferrell and his Swedish wife chose Matias for their second son.
 In the Bible, Matthias is the apostle chosen to replace Judas Iscariot. The Catholic and Eastern Orthodox churches honor Matthias as a saint.
 The Mathias spelling is used by George Eliot for the father of the protagonist of her novel Adam Bede.
 Matthias is popular abroad, and especially in Austria, France, The Netherlands, Iceland and Belgium, where it is normally pronounced Muh-TEE-us, though Americans are more likely to say Mah-THY-us.

Matthias

This name once seemed a bit grand and pompous for an American baby boy, but a significant number of parents are now preferring it as a substantial platform for the nickname Max, among them Jennifer Lopez and Marc Anthony, who chose it for their twin son.
 Maximilian was a traditional royal name among the Hapsburgs in Austro-Hungary and also in Bavaria. In literature, it appears as the husband of Rebecca in the eponymous novel and also in The Count of Monte Cristo. Maximilian Schell was a highly respected Austrian actor who won a Best Actor Academy Award in 1961.

Otto is cool again. Long a quintessential Old Man Name, Otto has been promoted to trending darling of adventurous baby namers. 
 Like most <a href="https://nameberry.com/baby-names/160/german-names">German names</a>, Otto fell out of favor during and after the two World Wars – it had been a Top 100 name in the years preceding. Off the Top 1000 from the mid-1970s until 2011, Otto is now headed straight uphill.
 <br/
There were some distinguished Ottos before the imperial image of Prussian Otto von Bismarck colored the name. Otto the Great is generally considered the founder of the Holy Roman Empire and there were several German and Austrian royals with the name. 

 Otto Frank was the father of Anne Frank, the young Jewish girl who wrote her famous diary during her family's years in hiding from the Nazis during World War II. She was killed in Bergen-Belsen concentration camp in 1945 and her father Otto typed and edited the diary himself to prepare it for publication. 

 Otto Hightower is a character in the Game of Thrones universe, played by Rhys Ifans in the HBO prequel House of the Dragon.

 Feminine forms of Otto include Ottoline, Ottilie, Odilia and Odette, all fashionable in the UK along with Otto itself.

Rainer is one of those <a href="https://nameberry.com">baby names</a> that is still under-the-radar but has been quietly gaining traction: The number of boys who've received the name has doubled in the past decade, to just under 50. Part nature name and part traditional <a href="https://nameberry.com/baby-names/494/german-names-for-boys">German name for boys</a>, Rainer can claim a place among the two-syllable r-ending baby names so fashionable for boys today.

Rainer

 Renata is back in the U.S. Top 1000 after decades away; she has a larger following in other countries.
 Writer/critic Renata Adler was a star among the literati. And Renata is a minor vampire character in the Twilight series.
 For those of you thinking nicknames, Renata might be a full name leading to the increasingly trendy "Wren".

Renata

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

You've got the red-nosed reindeer to transcend, but there are other distinguished personages named Rudolph, Rudolf, and Rudy.

Rudolf

Sophie is the French form of the Greek Sophia, for which it is also commonly used as a nickname. Given Sophia's long standing among the Top 10 girl names in the US, Sophie may feel more popular than it actually is.
 
Sophies are scattered throughout European royal history, including Sophie of Thuringia, Duchess of Brabant, Princess Sophie of Sweden, and in modern times, Sophie, Duchess of Wessex, the wife of Britain's Prince Edward. German-born Catherine the Great was born Sophie of Anhalt-Zerbst, but changed her name to Catherine upon her conversion to Russian Orthodoxy.
 
Sophie is Sophia's cuter, more irreverent near-identical twin. Which do you like better? And do you see them as virtually the same name or very different? While you definitely couldn't name sisters Sophie and Sophia, you may have both on your short list and consider them distinctly separate choices. Sophie is lively and down-to-earth, while Sophia is more sophisticated and buttoned-up. 
 
Sophie was the choice of both Eric Clapton and Luke Perry, as well as of Bette Midler for her now-grown daughter.
 Sophie Zawistowska is the Polish heroine of the iconic William Styron novel Sophie's Choice, played in the 1982 film by Meryl Streep—who would play the mother of a Sophie decades later in Mamma Mia!.

Sophie

Most religious form of this name, fading from use now.

Therese

Theresia

A solid classic with plenty of history, Thomas strikes the balance between strength and gentleness. A favorite in the UK, a staple in France, and Australia, and never absent from the US Top 100, Thomas feels like a safe bet and a name that fits into any era. 
The Greek form of the Aramaic name Ta’oma, Thomas means “twin.” It came about in the Bible because there were too many apostles called Judas, and so, Thomas became the “twin”, to reflect his close brotherhood with Jesus. 
Known as “Doubting Thomas” due to his initial skepticism of Jesus’s resurrection, he went on to become a martyr, and there was no need to doubt Thomas’s potential as a given name. 
Brought into common usage by the Normans, it was then always among the 5 most common English names for boys at any point between the 13th and 19th century. 
While it has fallen down the US charts in recent years, it remains a familiar and trusted choice. Given to over 6000 boys every year, it has made a steady climb back into the Top 50. 
Across the pond in the UK, both Thomas and Tommy make the Top 30, while Tom, Tommy-Lee and Tommie have made their mark in the Top 1000. 
As a well-established classic, Thomas naturally comes with plenty of noteworthy namesakes. “Thomas the Tank Engine” might appeal to you kids, but there’s also the theologian, Sir Thomas Aquinas, the cardinal Thomas Wolsey, the Founding Father, Thomas Jefferson. the philosopher, Thomas Hobbes, and the writer, Thomas Hardy. 
More recent namesakes for those who aren’t into history include actors Tom Hardy, Tom Cruise, and Tom Hiddleston, singers Tom Parker and Tom Fletcher, Olympic diver Tom Daley, and Thomas Sanders, of YouTube fame. 
A timeless all-rounder, Thomas comes with the intuitive nicknames, Tommy and Tom, which feel sweet for a child but not too cutesy for a grown-up. For more unexpected options, you could try the nature-inspired Moss or Scottish Tam. 
Unlikely to go out of style anytime soon, Thomas is a refined but approachable choice. If the popularity does give you pause, however, you could try the surname-inspired Thompson, or an <a href=“https://nameberry.com/list/492/100-classic-boys-names--below-the-top-1000/all”> underused classic</a> like Marius, Rufus, or Phinneas. 
Alternatively, there is a wealth of interesting variants to ponder, from Italian Tommaso and Scottish Tavish to Croatian Tomo– and for girls, there’s Thomasina, Tomine and Tamsin.

Thomas

A saint's name with a noteworthy literary background, including uses by Shakespeare in Two Gentlemen of Verona and Much Ado About Nothing, by Ben Johnson, Walter Scott, Longfellow, D. H. Lawrence and Neil Gaiman. In real life, her two most well known representatives are writer Ursula Le Guin and actress Ursula Andress. In literature, there is also Ursula Iguaran, a key, long-lived character in Gabriel Garcia Marquez's major work, One Hundred Years of Solitude.
 Caveat: Today's kids might associate this name with the campy, corpulent octopus in Disney's The Little Mermaid.
 Ursula ranked in the Top 1000 through 1983. Time for a comeback?

Ursula

The name of a martyred medieval saint, Valerie has been on the popularity list since its earliest publication in 1880. Though it peaked in the 1960s, remaining in the Top 100 until 1988, it still doesn't sound terminally dated; the association with the word valor gives it a sense of boldness and makes it one of the special group of <a href="https://nameberry.com/list/96/girl-names-that-mean-brave-or-powerful">girl names that mean strong</a>. 
 The original name Valeria, came into use in the 1890s, followed soon after by the French form Valerie, which rapidly became the more accepted form. In the 2011 werewolf update of Red Riding Hood, Red was given the name Valerie.

Valerie

The Viktor form of this classic name is widely used throughout Europe and is rising in the US as well.

Viktor

Wenzel

This dignified German form of William belonged to two German Emperors and Kings of Prussia, as well as a host of other important historical figures. These include composer (Wilhelm) Richard Wagner, philosophers Georg Wilhelm Friedrich Hegel and Friedrich Wilhelm Nietzsche, mathematician Gottfried Wilhelm von Leibniz, and physicist Wilhelm Roentgen, who discovered the X-ray. It now sounds rather dated in Germany, however, having dropped out of the Top 20 there in the late 1920s and continuing to decline since.
