Bubbly, bright, and versatile, Phoebe is a name with mythological, biblical, and literary ties. Used since the 17th century, it fell out of fashion in the US during the '60s, only to be revived after it appeared in the 90's TV favorite, Friends.

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.

Lyra is a name with ancient and celestial roots that's found new popularity thanks to its starring role in Philip Pullman's book series, His Dark Materials and its subsequent movie and TV adaptions. Simple yet starry, Lyra is familiar but not overused in the US, where it ranks in the Top 500.

The original oddball celebrity baby name, via Frank Zappa's daughter Moon Unit, who claims she's always liked it.

The name of the Roman goddess of the moon, Luna is derived straight from the Latin word for moon, luna. Luna may be the name most likely to surprise someone from an older generation by its Top 10 status in the US and its widespread international popularity.

The goddess name Aurora has consistently been on the US popularity list since the nineteenth century, but has really taken off in the past 30 years. Aurora also enjoys remarkable international popularity, ranking in the Top 100 throughout the English-speaking world as well as in Italy, Spain, Norway, Switzerland, and several other European and Latin American countries.

Stella is a name with star quality and sparkle, that manages to sound both ethereal and earthy. Celestial but not otherworldly, it lands somewhere between the popular Ella and bold Seraphina.

Elena is at its most popular point ever in the US, thanks to its cross-cultural appeal and the overall popularity of El- names. It's more international than Ellen or Eleanor, but still accessible.

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."

Maybe it's because she shares that winning -elle sound with Isabel and Bella, but Estelle is no longer seen as a muumuu-wearing canasta player of a certain age (think George Costanza's mother on Seinfeld or Joey Tribbiani's talent agent in Friends). This could be in part thanks to the young Royal Couple of Sweden, who chose it for their firstborn daughter, or the single-named British R&B singer. It reentered the US Top 1000 in 2012 after a nearly fifty-year absence.

Celeste is a softly pretty and somewhat quaint name with heavenly overtones, which kids might associate with Queen Celeste of Babar's elephant kingdom. She's a light and lovely choice that's finally getting noticed.

Helena is one of those classic names that just misses making the US Top 1000 girl names for its entire history, falling off for a single year in 1992. Since then it's been drifting lazily up the charts, and makes a perfect choice if you want a name that both fits in and stands out.

Esther was derived from the Old Persian word stāra, meaning "star." In the Old Testament, Esther, originally named Hadassah, was the captured Jewish wife of the King of Persia who risked her life to save her exiled people from annihilation. This story is celebrated by Jews on the holiday of Purim, so that it has traditionally been given to girls around that time.

Diana, the tragic British princess, inspired many fashions, but strangely, not one for her name. For us, Diana is a gorgeous and still-underused choice.

Selene may be the mythological Greek original, but Latin variation Selena is used more often in the US these days. Selene is the Greek goddess of the moon, sister of Helios the sun god. Selene is also sometimes called Cynthia and Phoebe. The name may be related to the word selas, which means light, and is one of the loveliest of the Greek goddess names.

Helen is a name that has connoted beauty since ancient times – Helen of Troy was the the mythological "face that launched a thousand ships," over whom the ten-year Trojan War was fought.

In Greek mythology, Nyx was a powerful goddess and the embodiment of the night, giving this name a dark yet mystical feel. While some may associate too strongly with the word nix (meaning "nothing", "refuse" or "put an end to"), or to the make-up brand Nyx, it was nevertheless chosen for 64 girls (and 26 boys) in the US in a recent year.

Most of us had never heard this lovely Welsh name with links to the moon until we heard the 1976 smash hit Fleetwood Mac song of that name, with lyrics by Stevie Nicks. That same year it popped onto the U.S. Top 1000 at Number 593.

Sleek and serious, yet bright and energetic at the same time, Cynthia appears in classic mythology as an epithet for Artemis or Diana. While it is now a more neglected choice, it was once hugely popular in the middle of the 20th-century, peaking at #7 in the US, and in the Top 20 by diminutive Cindy.

Selena is smooth, shiny, and sensual, a nineteenth-century name that found new life in the Latino community, following the biopic of slain Tejano singer Selena Quintanilla, starring Jennifer Lopez. But you don't have to be Latin to love Selena, which is both distinctive yet in step with stylish modern names such as Seraphina and Celia.
