Alya is most familiar in the US in its much-more-complicated form Aaliyah, the spelling used by the later singer. The traditional name of the star system Theta Serpentis, Alya is also an established Muslim first name and a Turkish place-name.  It may also be a Russian short form for Alexandra or any other Al- name.

Alya

One of the many international variations of the classic Helen.

Alyena

Anais, the name forever attached to the daring French-born American novelist and diarist Anais Nin, is unusual and French enough without appending an e, though some may think it clarifies pronunciation.

Anaise

An attractive Italian color and rock word name that doesn't sound anything like its meaning.

Ardesia

This name of the Cretan goddess of fertility is most popular now as the more melodic Ariana, but Ariadne has possibilities of its own. It first entered the US Top 1000 in 2014. The renewed interest in the name falls in line with the revival of other mythological names like Apollo and Athena. The trendy nickname Ari doesn't hurt either.
 In Greek mythology, she was the daughter of Minus who gave Theseus the thread by which he escaped from the labyrinth. After being deserted by him, she married Dionysus, the god of fertility, wine and drama

Ariadne

Arran Island (not to be confused with the Aran Islands in Ireland) is a large island in Scotland's Firth (or bay) of Clyde. Attractive name, long popular in Scotland, but elsewhere would be forever be mixed up with Aaron.

Astrid has been a Scandinavian royal name since the tenth century, and many people associated it with the Swedish author of the Pippi Longstocking stories, Astrid Lindgren. Astrid is derived from the name Ástríðr, which is made up of the Old Norse elements that mean "god" and "beautiful." 
Related names include Asta, a diminutive used throughout Scandinavia, and Astride, the French form. Despite their similarities, Astrid is unrelated to Astra, a Latin name meaning "of the stars."
 
Astrid has never really assimilated into our culture the way Ingrid did, but with the renewed interest in international names, Astrid might be worth consideration by parents with Norse roots. 
 
Astrid is the name of the teenage heroine of Janet Finch's 1999 novel White Oleander and has appeared as a character in How to Train Your Dragon and the TV shows Fringe and Once upon a Time.

Astrid

An interesting cousin of Natalie (the 'h' is silent) found in the Louisiana Cajun community, Athalie is the name of a tragedy by classic French playwright Racine.

Atticus, with its trendy Roman feel combined with the upstanding, noble image of Atticus Finch in To Kill a Mockingbird, is a real winner among <a href="https://nameberry.com/boys-names">boy names</a>. Atticus entered the US Top 1000 in 2004 and is a firm Nameberry favorite. 
 
The reason for the popularity of Atticus is less its ancient roots than Atticus Finch, the upstanding hero of To Kill A Mockingbird.. In fact so many people have been inspired by the character embodied by Gregory Peck that Atticus Finch was voted the greatest hero of American film by the American Film Institute. Harper Lee's recently-released novel Go Set a Watchman paints Atticus Finch in a less flattering light, though that doesn't seem to have impacted the rising popularity of the name.
 
Atticus derives from the Greek Attikos, meaning "from Attica," the Ancient Greek region that contained Athens. Atticus is a literary name in more ways than one. Before it became synonymous with Atticus Finch, the name Atticus was associated with Titus Pomponius Atticus, a Roman literary figure.
 Daniel Baldwin and Isabella Hoffman were ahead of the curve when they chose Atticus for their son born in 1996; since then Summer Phoenix and Casey Affleck named their little boy Atticus, and Tom Dumont made it the middle name for his son Rio.

Atticus

Aurelia is an ancient Roman name that's become a surprise hit in the contemporary world. A top favorite on Nameberry, it reentered the US Top 1000 in 2014 after a 70-year absence and continues to climb.
 
Aurelia is the female form of the Latin name Aurelius, an ancient Roman surname. Aurelius is derived from the Latin word aureus, meaning "golden," which was also the name of a gold coin used in Ancient Rome. Aurelius was a cognomen, a third name in Roman culture that often referenced a personal characteristic or trait, likely used for someone with golden hair.
 
The Roman classic Aurelius, from which Aurelia derives, was very common in the Roman Empire and is currently experiencing a resurgence in the US—it re-entered the Top 1000 list in 2012 after a 61-year hiatus. 
 
The name of several minor early saints, Aurelia's sound and feel can be credited for it being on the rise again. Aurora and Oriana are Aurelia cousins you might also want to consider. 
 
Aurelia was the name of the mothers of Julius Caesar, the writer Sylvia Plath, and Arnold Schwarzenegger, who, in her honor, made it one of his daughter Christina's <a href="https://nameberry.com/list/673/middle-names">middle names</a>.

This fanciful Irish extension of Bridget is known here through the wacky Amelia Bedelia books for kids -- an association your child may or may not like.

You say Bryn, he says Bryana -- here's a name you might agree on. 

Brynna

If you’re a fan of the annual animated Rudolph the Red-Nosed Reindeer, you’ll recognize the name of Rudolph’s beautiful doe sweetheart, pronounced cla-REES—uncomfortably close to the Silence of the Lambs pronunciation.  Clarice was the name of the wife of Lorenzo de' Medici, and Clarice Cliff was a famed British ceramics artist. Though a Top 300 name from 1906 to 1934, modern parents might prefer the more delicate Clarissa.



Clarice

This version softens, feminizes, and glamorizes the long-time favorite. A fresh way to honor Grandma Betty. Elizabetta is a variation.


Elisabetta

More unusual than Fiona and more user-friendly than Fionnuala, the engaging Scottish Fenella, has been scarcely heard in this country.
 Fenella first became known outside of Ireland when Sir Walter Scott used it for the character Finella Christian in his novel Peveril of the Peak.
 Finola is another underused Anglicization of Fionnuala.

Fenella

Hermione's costarring role in Harry Potter has made this previously ignored, once stodgy name suddenly viable. Hermione could really take off once today's children start having kids of their own. 
 In ancient Greek myth, Hermione is the daughter of Spartan King Menelaus and his wife Helen; in pre-Potter lit, the name appears in Shakespeare's The Winter's Tale and in Walter Scott's novel The Fortunes of Nigel.

Hermione

The luminous Ingrid Bergman's appeal was strong enough to lend universal charisma to this classic Scandinavian name, which has been somewhat neglected in the US. Even today, a child named Ingrid would be assumed to be of Scandinavian ancestry, signaling the name has never been fully integrated into the English lexicon the way other European choices from the same era like Danielle or Kathleen have.
 Still popular in its native Scandinavia, where it is a royal name, its highest US ranking was Number 380 in 1967. 
 Its meaning refers to Ing, the Norse god of fertility, peace, and prosperity, and he's looked upon as the ancestor of the Swedish kings.
 Ingrid was the name of mother figures in both Spy Kids and White Oleander.
 Trivia tidbit: It's Scarlett Johansson's middle name.

Ingrid

Isabetta is a charming spin on both the Elizabeth and Isabella families and a new way to go if you love the originals but want something more, well, original.

Now that Tristan has been rediscovered, maybe it's time for his fabled lover in the Arthurian romances and Wagnerian opera, a beautiful Irish princess, to be brought back into the light as well. 
 This would make an artistic and romantic choice, as the medieval heroine is seen as a symbol of undying love. 
 In Marilyn French's novel The Women's Room, the character Isolde is nicknamed Iso. Isolde is currently a Top 500 name in the Netherlands. Variations include Iseult, Isolt, Isoud, Isolda and Yseult.

Isolde

Jessamine, a charming name occasionally heard in England, is just beginning to be appreciated in the U.S. as a possible successor to all the Jess names of the past. It's also spelled Jessamyn, as in Quaker novelist Jessamyn West, author of Friendly Persuasion--who started life with Jessamyn as her middle name.
 Jessamine began to be used as a first name in Britain around 1900, along with other flower-related names. Yasmin and Yasmine are other Jasmine variations.
 This would make a great choice as a namesake honoring a Jessica.

Jessamine

Loki is the shape-shifting, gender-bending god of mischief in Norse mythology.  Taking several animal forms, from a salmon to a seal to a fly, Loki is alternately friend and foe of the gods.

The lovely Lorelei, a name from old German legend, was a beautiful Rhine River seductress whose haunting voice led sailors to hazardous rocks that would cause them to be shipwrecked. And this siren image clung to the name for ages.
 Lorelei was the name of the gold digger portrayed by Marilyn Monroe in Gentlemen Prefer Blondes in 1953, then went underground for half a century before it was popularized by TV's The Gilmore Girls in 2004.
 The name itself had a starring role in the show, used for the mother, daughter, and even the grandmother. Spelled Lorelai, the characters used three different nicknames: Rory for the daughter, Lori for the mom, and the seemingly unrelated Trix for grandma.
 Beyond the influence of the show, Lorelei is benefiting from the popularity of <a href="https://nameberry.com/search/girls-names/l">girls' names starting with L</a> -- and two Ls are even better than one.

Lorelei

Lyra is a name with ancient and celestial roots that's finding new popularity thanks to its starring role in Philip Pullman's His Dark Materials series, seen in the movie The Golden Compass. Simple yet unique, Lyra hits the sweet spot between too popular and too unusual.
 
Lyra is a constellation name taken from the lyre of Orpheus. It contains the star Vega and thus could make a melodic choice for a parent interested in music, astronomy, or mythology. It has more depth and history than Lyric, is more unusual than Lila (which it rhymes with). It debuted in the US Top 1000 in 2015.
 Lyra was chosen for their daughter by Ed Sheeran and Cherry Seaborn, as well as Sophie Dahl and Jamie Cullum. And then there's Lyra Belacqua, the heroine of His Dark Materials and The Golden Compass.

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

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.

Sebastian

Sirius

Name of the Phoenician deity who was the patron of Carthage, goddess of the moon, and a fertility figure.  Variations include Tanit, Tanis, and Tanitha.  The name is frequently misinterpreted to be an Irish name meaning "estate."  Despite this august heritage, the original form of the name is a bit lispy for use in modern English-speaking lands.
