Althea is a poetic, almost ethereal name found in Greek myth and pastoral poetry, associated in modern times with the great tennis player Althea Gibson, the first African-American to win at Wimbledon. 
 
Althea appears in Greek mythology as the mother of the hero Meleager and was revived by the seventeenth-century poet Richard Lovelace as a poetic pseudonym for his beloved.
 
These days, parents would also appreciate the short form Thea.
 
Althea is the most common girl name in the Philippines.

Annette is a French diminutive of Ann which was among the first wave of widely-used girls' names from France, now neglected for so long that it's almost starting to feel stylish again.

This evocative name of one of the Three Wise Men of the Orient, also spelled Balthasar, may finally be ready for prime time. Balthazar, Melchior and Caspar were the Magi who brought gifts of gold, frankincense and myrrh to the baby Jesus, though their names were not mentioned in the Bible.
 Balthazar, in its various spellings, has been attached to a number of distinguished artists, writers and philosophers of the past; the most prominent contemporary bearer is Balthazar Getty, actor and great-grandson of J. Paul Getty. The iconoclastic modern painter Balthus was born Balthasar.
 Balthazar is well represented in literature. The name appears in no fewer than four Shakespeare plays, is the title of a Lawrence Durrell novel, is the main character of a Balzac novel, and has been seen in everything from a James Bond film to Buffy the Vampire Slayer to The Smurfs to Xbox and online games, and there is a J. P. Donleavy novel titled The Beastly Beatitudes of Balthazar B.

The childhood name of the heroine of Memoirs of a Geisha is pretty and accessible. Chiyiko is a pet form.

Claude is a soft-spoken French name that conjures up the pastel colors of Monet and harmonies of Debussy. In France, it is used for girls as well, in fact in the Tracy Chevalier novel Lady and the Unicorn, the protagonist is a female Claude.
 Claudes have appeared in such iconic movies as Chinatown and Close Encounters of the Third Kind. Actor Simon Baker has a son named Claude Blue.
 A French classic, Claude was also a top 100 name in the U.S. until 1922.
 The attractive Italian version Claudio is occasionally heard in this country, and Claudius is the original Latin--which could be restored in the current Latin-loving climate. While "lame" is the most widely-acknowledged meaning, some etymologists theorize that the name may relate to the word for enclosure or clause, an alternate meaning that may appeal to a child with a form of this otherwise-appealing name.

Eve, the oldest name in the Book, is now coming back into style, having the virtues of simplicity and purity, yet with more strength and resonance than other single-syllable names like Ann. British actor Clive Owen chose Eve for his daughter, as did Jessica Capshaw. 
 
While Eve is compromised by its similarity to trendy sisters Ava, Eva, Avery, Evelyn, Evie, ad infinitum, it still has them all beat with its streamlined classic style.
 The rapper born Eve Jihan Jeffers goes by the mononame Eve.
 Fictional Eves have figured prominently in the films All About Eve, Three Faces of Eve, and WALL·E, and on TV in Angel and Xena: Warrior Princess.
 Eve is the anglicized form of the Gaelic Aoife.

When it's spelled with two dots over the 'u' in German, Gunther is pronounced GUWN-ter, but it has a much softer sound when the 'h' is voiced by English-speakers, as it was, for example, for the name of a character in Friends.
 Gunther has never been as well used in this country as the Scandinavian version, Gunnar, which now ranks at Number 502, making Gunther all the more distinctive.
 Well-known Gunthers include German novelist Gunt(h)er Grass and the character in the German epic poem Die Nibelungenlied, which formed the basis for Richard Wagner's Ring cycle of operas.

Gunther

While Gwen may have originated as a short form of Gwendolen and Gwendolyn, these days it frequently stands on its own. Rocker Gwen Stefani has given it a shot of cool, and parents are choosing it as a standalone more and more often—Gwen hopped back onto the US Top 1000 in 2013 after an absence of over 30 years. Gwen could also be short for Guinevere.

Isaiah, like brethren Isaac and Elijah, is a once neglected biblical name now firmly back in favor, already surpassing such long-popular Old Testament stalwarts as Aaron and Adam. Isaiah has ranked on the US Top 1000 list for boys every year but two, 1969 and 1970.
 Isaiah derives from the Hebrew Yesha’yahu, containing the elements yasha’, meaning "to save," and yah, in reference to the Hebrew god. The biblical Isaiah, son of Amos, was the most important of the major prophets, with an Old Testament book named for him. He prophesied that the Children of Israel would be exiled from their homeland, but that God would bring the back.
 
Isaiah has been a star player on the contemporary athletic field, with several prominent basketball and football player namesakes, in addition to a memorable character on Little House on the Prairie, and Grey's Anatomy actor Isaiah Washington.
 Beyond that, two sports figures have named their sons Isaiah: Allen Iverson and Tim (and wife Elisabeth) Hasselbeck. Basketball superstar Isiah Thomas helped popularize that streamlined spelling of the name.

Ivor, a favorite choice for upscale characters in Brit Lit novels by authors like P.G. Wodehouse and Evelyn Waugh, is an interesting and unusual name just waiting to be discovered by parents in this country. 
 Ivor Novello was the stage name of a popular Welsh actor and songwriter of the recent past who brought it to prominence in England.
 An equally appealing name is the related Ivo, which has the energetic impact of all names ending in 'o'.

Though it sounds like a chopped-off variation of Olivia, which means olive, the distinctively attractive Livia has been an independent name since the days of the ancient Romans, when it belonged to Livia Drusilla—the powerful wife of the Emperor Augustus—and is still commonly heard in modern Italy. 
 Livia was a literary favorite from the sixteenth century, appearing in the plays of John Fletcher and Thomas Middleton, and playing a minor role in Romeo and Juliet. Anna Livia Plurabelle is the name of a character in James Joyce's Finnegans Wake.
 Livia entered the US Top 1000 in 2004 but unlike its popular sister Olivia, it's never risen that high in the ranks. But Livia is a Top 100 girls' name in many other countries, including France, the Netherlands, Brazil, Sweden, Switzerland, and Austria.

Livia

Most contemporary English speakers will hear the name Lyssa as short for the long-popular Alyssa or Melissa. But Lyssa is a bona fide Greek mythology name, though not a very appealing one.
The goddess Lyssa could not control her rage. Choose this otherwise soft and pretty name at your own peril.

Lyssa

Reggae master Bob's surname was one of the biggest risers on the popularity charts for girls in 2008, with spellings Marlee and Marely also leaping in favor. Also used for boys, Marley is one of the <a href="https://nameberry.com/unisex-names">top unisex names</a> in the US.

The bright, playful Micah feels like the middle ground between the safe, solid qualities of Michael and the flair and energy of Luca. Both Biblical and stylish, Micah is proving popular among parents today. 
A shortened form of Micaiah, Micah is an Old Testament name, meaning “who is like the Lord”. The biblical figure is a minor prophet who denounced oppression from the ruling classes and alternated between prophecies of doom and hope. 
Micah was among the Old Testament names revived by the Puritans in the 17th century, and it was used by early Pilgrim settlers in America. It wasn’t until the 1970s, however, that it really saw significant usage. 
Entering into the Top 200 back in the 80s, Micah has since made a slow and steady climb to the Top 100. Given to over 3000 boys – and 200 girls – each year, Micah now feels established but not overused. 
In pop culture, Micah has been used for characters in the animated series She-Ra: Princess of Power and in television show Heroes. It was also selected by Arthur Conan Doyle as the central character for his non-Holmes novel, Micah Clarke. 
Other noteworthy namesakes include Micah Hyde, an American football player, Micah Kogo, a Kenyan long-distance runner, and Micah Richards, an English footballer. Celebrities including actress Sarah Drew, basketball player Moses Malone, singer Lauryn Hill, musician Willie Nelson, and singer Neil Diamond all have sons called Micah. 
Popular in New Zealand and climbing the UK charts too, Micah makes a sleek but sparky choice for anyone honoring a Michael or wanting a name with history that still feels fresh. 
If you like Micah but prefer something outside the Top 100, or just want more inspiration, you could try a lesser-known <a href=“https://nameberry.com/list/456/unusual-biblical-baby-names”> Biblical name</a>, like Nekoda, Neriah, Tekoa, Zaccai, Ira, Jethro, or Jarah.

Orion is a rising star, with both mythical and celestial overtones.
 The Greek mythological Orion was the legendary hunter who pursued the seven daughters of Atlas, was slain by the goddess Artemis, and then placed as one of the brightest constellations in the night sky by Zeus.
 Mark Twain had a brother named Orion, and Chris "Big" Noth picked the name for his son. It is also a Harry Potter name.
 Orion's Gaelic connection to O'Ryan/Ryan makes it familiar as well as unusual.

Orion

Clad in armor. But while this name may have been forbiddingly antiquated not that long ago, the connection to the trendy nickname Os or Oz makes it a real possibility. 

Osric

Old-style creative name of the Greek mythological earth mother of all the gods. A lot better than the Roman equivalent: Ops. Rhea reentered the US Top 1000 in 2015. Its only previous appearance on the list since 1968 was 2004.
 Rhea Perlman is an American actress known for her role as Carla Tortelli on Cheers and as the wife of Danny DeVito.

Jewish parents in particular may be drawn to this quiet, composed name of the first king of Israel and the name of Saint Paul before his conversion. In modern times, it has been associated with Nobel Prize-winning novelist Saul Bellow. Its meaning makes it appropriate for a long-awaited child. 

Saul is a character in a John Dryden poem, and heard in the Handel oratorio, "Saul."
 Some other Sauls of note: Saul Steinberg, known for his iconic New Yorker covers, and graphic artist/movie credit designer Saul Bass. The birth name of Guns n Roses's Slash is Saul Hudson. On recent TV, there have been Sauls on Breaking Bad and Homeland.
