Stardust and Moonbeams

While Danica may sound similar to Dana, Danielle, and Daniela, Danica is not a variation. Danica, a delicate and unique Slavic name meaning "Morning Star," is synonymous with Venus in many countries.

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.

In Greek mythology, Elara was a lover of Zeus who gave birth to a giant son (ouch); it's also the name of one of the moons of Jupiter, giving it a celestial feel. Possibly derived from the Greek alara meaning "hazelnut" or "spear", it combines that favorite El- beginning with the popular -ara ending of Clara, Lara, and Amara, making it an all round appealing choice. Currently in the UK Top 1000, and on the rise in the US, it could be a fresher or less popular alternative to Ella, Lyra, or Laura.

Eos -- that's pronounced with a short e like eros without the r -- is the Greek Titan of the dawn. Any ancient name with a sleek modern feel has definite revival possibilities. Eos could be an inventive way to honor grandma Dawn.

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.

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.

Bright and vibrant but elegant too, Estrella is a rising star among Hispanic families that would make a good cross-cultural choice too. A Spanish word name that literally means "star", it is similar to other popular names with the same stellar meaning such as Esther and Stella.

The name of the young Greek sun god, brother to the moon goddess Selene, who rode across the sky each day in a chariot pulled by four horses.

The disgraced heroine of The Scarlet Letter's name, after long neglect, just might have a chance at revival, following in the wake of sister-name Esther. We've characterized her elsewhere as an eccentric aristocrat, much more accepted in the U.K. than she has been here.

Io may be one of the slightest names in the book, but there aren't many two-letter names with as much substance as this Greek mythological example. Io, a name used for the largest moon of Jupiter, was in classic myth raped by Zeus and escaped from him by changing herself into a cow.

Iris has so much going for it. It's a fashionable flower name. It's a mythological name, from the Greek goddess of the rainbow. And it's a classic name, always ranking in the girls' Top 1000 but now at its highest point ever.

Used more for girls in Europe, but definitely sounds masculine enough for a boy here.

A biblical place name with trumpeting verve and strength.

Jupiter's partner Juno has entered the mainstream, so it's possible that her divine mate could follow. But not necessarily for boys — Jupiter is currently mostly female in the US, thanks to its similarity to Juniper. Stars including Ed Sheeran and Ashley Tisdale recently welcomed daughters named Jupiter, which could shift the balance even more towards the girls.

Leo is a strong-yet-friendly name that was common among the Romans, used for thirteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

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.
