Calista Flockhart spotlighted this lovely Greek name that has a long future in the English-speaking world. Kallista is another spelling; Calixta and Calixto are related.

Clio is the name of the ancient Greek mythological muse of history and heroic poetry, one that is rich with modern charm and would make an intriguing choice, especially thanks to its dynamic o-ending.

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.

Cassiopeia, the name of a mythological mother who became a stellar constellation, is challenging but intriguing, and has all those softening Cass nicknames available. And with all names Cass-related trending, Cassiopeia may be an unusual route to a stylish name.

Spelled with either one 'l' or two, Calista came to the fore in 1997 when Calista Flockhart hit it big as Ally McBeal. Flockhart, who bears her mother's middle name, didn't just introduce a name, she introduced a whole sensibility. Pretty and delicate, Calista is definitely worthy of consideration, especially for parents with Greek roots.

Sometimes used as a short-form of Catholic Pope name Anacletus, Cletus is an ancient name that has not-yet found the popularity of Theodore, Leo, Atticus and Max. It perhaps suffers from its association to the yokel character in The Simpsons , but we think it's time for a reconsideration, given how well it fits into several current trends. Nickname Clete is cute as a button!

Cyane is a mythological Sicilian nymph who lived in a pool and whose name is an intriguing twist on the color name trend.

Forget the oil. It's one of the twins that make up the constellation Gemini, and a mythological name on the cutting-edge of fashion; used by Metallica's James Hetfield.

With a long and noble history -- Cyprian was one of the great Christian Latin writers -- this could make a highly unusual but meaningful choice.

Reference to the mythological Three Graces of womanly charm, this one representing charity. Pronounced in Greek as starting with a back-of-the-throat H sound, most English-speakers would translate that to something closer to KAR-is. It's also the name of a girl who lived in Atlantis in the novel Taliesin, and appears in the Margaret Atwood novel The Robber Bride.

Calixto is known in Spain as the name of three popes, one of whom was the martyr, Callixtus I, regarded as a saint. Calixto has a lot of energy and futuristic spirit, thanks in part to the attention-grabbing 'x.' He is the main character in the Spanish classic, Fernando de Rojas's Tragicomedy of Calixto and Melibea.

Delicate and gentle old-fashioned name, the kind found in early English poetry. While Corinna and the original Green Korinna are technically diminutives of the ancient Kore, now the popular Cora, this name will often be mistaken for other similar-sounding though unrelated names, such as Karenna. But it's pretty and is backed by more tradition than you'd guess.

Trending down, along with others of both the Car and the issa groups.

Cadmus is the name of the serpent-slaying hero of Greek mythology who also founded the city of Thebes and is credited with inventing the alphabet.

Another of the new Greek-accented Cal- names.

Though Collins makes the Top 1000 for girls, it sounds strong and handsome for boys too, kind of like the newly-stylish Brooks. The final s updates it from the 80s-ish Colin or the Twilightish Cullen. Might make an innovative honorific for a grandpa Nick.

Rhythmic route to the nickname Cal. This musical moniker is another great example of a traditionally feminine name that could easily go masculine.

Calista Flockhart opened the door to a whole flock of graceful and unusual Greek names like this, including Calantha, Calla, Carissa, and Cassia. Calandra itself is the name of a species of lark, and has the versatile nickname options of Callie, Candy, Andra, Andie and Birdie.
