Iridescent Siren

An interesting unisex possibility, with an air of mystery connected to the Delphic Oracle, the most important oracle in ancient Greece; it was also a major site for the worship of the god Apollo.

Delphine is a sleek, chic French name with two nature associations — the dolphin and the delphinium, a bluebell-like flower, a well as a link to the ancient city of Delphi, which the Greeks believed to be the womb of the earth. All of these derive from the Greek word delphus "womb".

Diamanta is a version of Diamond that is sometimes heard in France, and does soften the hardness of the stone, but lacks authenticity.

Echo, the pretty, resonant name of a legendary nymph, was the heroine of Joss Whedon's sci-fi series Dollhouse. Nick Hexum, of the band 311, named his daughter Echo Love.

Variation of Ilithyia.

Less known than other Cornish beauties like Demelza, Elowen and Kerensa, Elestren is a pretty Cornish botanical name ripe for wider usage.

Eleusine is the botanical name of genus of grasses found across Africa and Asia. It also has a lovely soft sound and look. This might be a great choice for nature lovers or African or Asian parents looking for something with heritage meaning that's still quite unusual. Bonus points for its very fashionable "El" beginning

An Anglo-Saxon name borne by the queen of Alfred the Great. American novelist Helen Ricker wrote under the pen-name Elswyth Thane. Variants include Elswith, Ealswith and Ealhswith.

This version stands out from the pack of Alyssas, Elissas et al, as Elysia relates to Elysian Fields, the mythological home of the blessed.

Endellion is the name of an early saint who was a daughter of King Brychan and goddaughter of King Arthur whose life is commemorated by the Cornish village of St. Endellion. This intriguing ancient name was brought into modern usage by British Prime Minister David Cameron, who used it as one of the middle names for his fourth child, a baby girl.

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.

Rising star among Hispanic families that would make a good cross-cultural choice. A morepopular name with the same stellar meaning is Esther

Eurynome was a name given to almost a dozen characters in Greek mythology. Among the most notable are Eurynome, mother of the Charites, and Queen Eurynome, wife of King Ophion.

This lovely compound name blends two of the most stylish girl names of the moment. The result has a pretty and sophisticated sound, reminiscent of stylish rarities like Evelina.

A popular name in the Middle Ages, Evelina was eclipsed by Evelyn in the last century, but has a chance at a well-deserved comeback now, fitting right in with the other Ev-names. Like Evelyn, it derives from the Norman name Aveline.
