Andreas is a beautiful name, with the patina of an Old Master painting, one that could make a dashing namesake for an Uncle Andrew. 
 In Europe, Andreas is currently in the Top 20 in Norway and is also popular in Denmark, Sweden, Germany, and Austria.
Some other international variations of Andrew you might want to consider — Andre, Andrei, Andres, Andrea, and Anders.
 Notable namesakes include photographer Andreas Feininger. One not-so-pleasant association: the San Andreas fault line in California.

Anya is a Russian variation of Anna, which came from the Hebrew name Hannah. Anya is the form found most frequently in Russia, Poland, and other East European countries, while Anja is the spelling usually preferred in Germany Norway, Denmark, Germany, Sweden, and The Netherlands. In the Hungarian language, Anya also means mother.
 
It is often used as a character name with a bit of foreign flair. Aside from its authentic use in Chekhov's The Cherry Orchard, Anya has appeared as Audrey Hepburn's name in Roman Holiday, on Buffy the Vampire Slayer, and as the latest Spider-Girl, who is also known as Arana. In literature, Anya Seton is the pen name of Ann Seton, author of such best-selling mid-century historical novels as Dragonwyck.

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

Charles derives from the Germanic name Karl, meaning "man" or "free man", and is a royal name in multiple European countries. A famous early bearer is Charlemagne, King of the Franks and Lombards and then Roman Emperor in the 8th-9th centuries. 
 
The word for "king" in several languages, including Slavic, Russian, and Polish, came from Charles. And, of course, Charles III is the current king of Great Britain.
 
Charles is a longtime traditional favorite that was in the Top 10 until the 1960s. Though not as popular as it once was, it's still a widely used name. 
 
The most fashionable form of Charles today is Charlie, used almost equally for girls and boys. And of course, Charlie or Charley is still used as a short form for Charles, along with the old school Chuck and new school Chas/Chaz.
 
Lately, Charles has been resuscitated by many celeb parents, from Jodie Foster to Russell Crowe, honoring a distinguished history dating back to the emperor Charlemagne—the original Charles the Great. 
 
Charles has been so well used for so long that it is virtually faceless—it can conjure up anyone from Dickens to Chaplin to Bronson. It has been an elegant royal name—designating both Bonnie Prince Charlie, leader of a 1745 rebellion, and the present king, as well as previous kings of France, Spain, England, Portugal, and Hungary. 
 
Among the well used international versions of Charles: Carl, Carlo, Carlos, Karel, Xarles, Charlot, and Siarl.

In ancient Rome, Cornelia was considered the paragon of womanly virtue, making it a handsome name with an excellent pedigree. It's rare today, so if you want a name no one else is using, somewhat reminiscent of Amelia and the Shakespearean Cordelia, Cornelia should be on your list. Cornelia's short forms might include Cora, Nelia or Nell--anything but Corny.
 The name of the mother of famous second century Roman reformers, Cornelia emerged in England in the seventeenth century, probably brought in by Dutch immigrants. The painter Jan Vermeer had a daughter named Cornelia.
 Cornelia has not made a mark on the U.S. popularity list since 1965--so she's more than due for reconsideration. In the meantime, it's been associated with contemporary socialite Cornelia Guest, giving the name an elite image.

Cornelia

Dorothea is a flowing and romantic Victorian-sounding name which was popular in the early decades of the twentieth century, but has been off the charts since 1970. Definitely on the brink of a revival!
 Dorothea has had a long literary tradition, including as a clever, beautiful character in Don Quixote and the idealistic heroine of George Eliot's Middlemarch.
 Worthy namesakes include Dorothea Dix, nineteenth century activist for the mentally ill and Civil War nurse, and the influential documentary photographer Dorothea Lange, known for her moving portraits taken during the Great Depression.
 Appealing nickname possibilities include Dorrie, Doro, Dodie, Dot, Dottie and Thea.

Dorothea

Ancient martyr's name that, though not especially appealing, might still be mildly possible, especially for Anglophiles. It was widely used in early Scotland, but was overtaken by its nickname, Effie.

Considered ultra debonair in the silent-movie era, Gilbert then went through a nerdy phase, a la Gilbert Gottfried. Now though, like Albert and Alfred and Walter and Frank, it could be in for a style revival. 
 Gilbert has always been on the US popularity list, reaching as high as Number 90 in 1930. The Normans introduced Gilbert to England, where it was common during the Middle Ages; it was the name of a 12th century English saint.
 Gilberts have appeared in such books as Henry James's Portrait of a Lady, Lucy Maud Montgomery's Anne of Green Gables, and Ayn Rand's Atlas Shrugged, and on screen in The Incredibles and as embodied by the young Johnny Depp in What's Eating Gilbert Grape?. The most famous portrait painter of George Washington was Gilbert Stuart. 
 Nickname Gil could come back along with Hal, but even more appealing are Gib or Gibby.

Gilbert

Stalwart Italian classic, completely at home in this country.

Guinevere was the name of the beautiful but ill-fated queen of Camelot, for so many years eclipsed by its modern Cornish form Jennifer. Today, Guinevere could be a cool possibility for adventurous parents intrigued by this richly evocative and romantic choice.
 Guinevere shares the attractive short form Gwyn with Gwyneth. Other cousin ideas: Gwendolen, Genevieve, Jenna, or Gwen.

Guinevere

Jeremiah is a solid Old Testament prophet name that has gradually taken the place of the now dated Jeremy, Gerard and Gerald, joining other currently popular biblical 'iah' names like Josiah and Isaiah. In the Bible Jeremiah is a famous prophet whose story is recorded in the book named after him.
 Dickens used the name in two of his novels--Little Dorrit and A Tale of Two Cities-- and other fictional Jeremiahs have been spotted in such movies and TV shows as Oz, Zoey101 and The Princess Diaries. Leonard Bernstein composed a work called Jeremiah Symphony.
 Caveats: Once-logical nickname Jerry sounds like the family dentist, and some may make the Jeremiah bullfrog association.
 A related, more unusual biblical option: Jeriah.

In Arthurian legend, Lancelot was one of the most dashing of the Knights of the Round Table who eventually had an affair with Queen Guinevere: it makes for a romantic story-- but perhaps overly romantic-- name.

 An older spelling is Launcelot, as seen in Shakespeare's Launcelot Gabbo in The Merchant of Venice and two Tobias Smollett novels.

 Short form Lance has had an independent life of his own.

Frilly and fit for a princess, but with plenty of spark and flair, Liliana holds international appeal and a modern glamor. Joining Lily and Lillian in the US Top 100 for the first time in 2022, Liliana is a fast-rising choice for girls. 
The Latinate form of Lillian, Liliana has two separate roots. It originally emerged from a 16th century diminutive of Elizabeth, with the meaning “God is my Oath,” and this lends the name a more solid and regal air. 
Perhaps the more obvious and popular origin for Liliana though, is as an elaboration of Lily, from the Latin word “lilium”, giving it a pretty, bright and floral feel. 
A favorite among the Hispanic community, Liliana is also trending in Czechia, Hungary, and Poland. But it is a name that crosses cultures, as demonstrated by its recent popularity in the US, and its upward climb on the English and Welsh charts. 
Notable Lilianas include the actress Liliana Mumy, who starred in Cheaper by the Dozen and the film director, Liliana Cavani, who created The Night Porter. Lilliana Ketchman of Dance Moms fame is another well-known bearer, albeit with a slightly different spelling. 
Sophisticated but sweet, Liliana is chosen for more than 2500 girls in the US every year and if it continues on the same trajectory, could one day catch up with the Top 50 choices. Lily and Lillian. 
With 10 members of the “Lily” family in the US Top 1000, and several “-ana” names ranking highly, Liliana certainly makes a stylish and on trend choice for a baby girl today. 
If you want your Lily to stand out however, Lillia, Lilium, Lilias and Lilibet are currently less popular options. Alternatively, Anneliese, Liviana, and Linnea could be worth exploring.

Liliana

This Welsh surname was taken up as a first in the English-speaking world in the early twentieth century, originally as a nickname for someone gray-haired. The original Welsh name was Llwyd, and pronounced LHOO-eed.  Beau Bridges was christened Lloyd after his actor father.

Lelouch

A midcentury Catholic classic that's not chosen by many parents today. Leonard Cohen fans might think of the beautiful song So Long, Marianne, named for his lover and muse Marianne Ihlen.

 The meaning of Marie 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).

Marianne

Milly and her more popular sister Millie are adorable Old Lady nickname-names springing back to life. Nearly 100 baby girls were named Milly, just Milly, last year, and Millie is in the US Top 500. Milly is the Molly of the new generation.

Milly

This saintly name--she was the mother of St. Augustine--plummeted after the double whammy of Lewinsky and the demise of Friends. 

Monica

Naomi was once a primarily Jewish name from the Old Testament that referenced the mother-in-law of Ruth. Because of this, it is a symbolic name given to girls on Shavuot when the story of Ruth is read in the synagogue. 
The French version is Noemie, in Italian Noemi. Naomi also has separate Japanese origins as a unisex name meaning "straight and beautiful."
 
This long-quiet Old Testament name seems to finally be finding favor with parents seeking a biblical name with a soft, melodic sound and a positive meaning, suddenly sounding fresher than the widely used Sarah, Rachel, and Rebecca. It's now more popular than ever after breaking the Top 100 for the first time in 2010. 
 
Beautiful black model Naomi Campbell and blond actress Naomi Watts have helped the modernization. Other namesakes are singer Naomi Judd and feminist writer Naomi Wolf.

Naomi

Nina is as multiethnic as you can get: Nina is a common nickname name in Spain and Russia, a Babylonian goddess of the oceans, and an Incan goddess of fire. Here and now, it's a stylish possibility that's been underused. "Weird Al" Yankovic chose this decidedly nonweird name for his daughter.
 Nina has been a permanent resident on the Social Security list, mainly in the low hundreds. 
 In literature, Nina Zarechnaia is one of the principle characters in Chekhov's drama The Seagull, as well as appearing in Trollope's Phineas Finn and Evelyn Waugh's Vile Bodies.
 More recent real-life bearers have included jazz singer Nina Simone (born Eunice) and Nina Garcia of Project Runway fame.
 Natalie Portman was awarded an Oscar for her role as ballerina Nina Sayers in the 2010 Black Swan.

Nina

The name of the brave, resourceful hero of Homer's epic saga has almost always been considered too weighty for a child to bear, but at this point, some brave, resourceful parents out there might be willing to take it on.

Rollo is a livelier, roly-poly, o-ending version of Roland. 
 Although it sounds modern, Rollo actually was seen regularly on Latin documents in the Middle Ages, though not heard in everyday speech. Historically, it's associated with a powerful Viking leader--who had a wife named Poppa. 
 Rollo May was a well known existential psychologist. There have been Rollos on screen played by Buster Keaton ("The Navigator"), Rainn Wilson ("Juno") and John Cleese ("Fierce Creatures").
 Rollo has also been used over the years as a pet form of Roland, Rudolph and Ralph.

Shirley Temple almost single-handedly lifted the gloom of the Great Depression, and in tribute (and perhaps wishing for a similarly curly-headed, dimpled darling of their own), thousands of parents of that generation gave their little girls her name. In 1935, Shirley was the second most popular girls' name in the country with more than 42,000 babies named Shirley.

 In an earlier time Shirley was used primarily for boys, but the tide turned with the publication of Charlotte Bronte's novel Shirley in 1849, the story of a character whose parents had selected the name for a boy child, then decided to use it anyway when he turned out to be a she.

 In addition to Shirley Temple, there have been Shirleys MacLaine and Jones and writer Shirley Jackson, as well as rocker Shirley Manson.

Shirley

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!.

Tristan -- known through medieval legend and Wagnerian opera -- has a slightly wistful, touching air. This, combined with the name's popular "an" ending, makes Tristan very appealing to parents seeking a more original alternative to Christian.
 One influence was the character Tristan Ludlow played by Brad Pitt in the 1994 movie Legends of the Fall, based on a Jim Harrison novel.
 Tristan is a dragon-slaying hero of Celtic legend, whose story was incorporated into Malory's Le Morte d'Arthur, in which Tristan is one of the Knights of the Round Table, consumed by his doomed love affair with Queen Isolde. Wagner set the story to music in his opera Tristan und Isolde.
 Tristan and its alternate form Tristram have been found in later lit as well. Tristram Shandy is a famous early comic novel by Laurence Sterne (in which the hero's father calls Tristram the worst name in the universe); Tristan is a major character in James Herriott's All Creatures Great and Small, and there is an eponymous novella by Thomas Mann.
 Particularly popular in Canada, Tristan was chosen for their sons by Travis Tritt, Wayne Gretzky, Natasha Henstridge and, most recently, by Elsa Pataky and Chris Hemsworth. Basketball player Tristan Thompson hails from Canada.
 Other variants of Tristan include Tristen, Tristin, Triston and Tristian.
