This Celtic goddess and Arthurian name may sound terminally old-ladyish to many ears--but so did names like Ella and Etta not so long ago. So Enid is yet another forgotten four-letter E-possibility: she's has been M.I.A since 1954.

Floral, bright, and subtly powerful, Gaia is a name with two separate origins. In Greek mythology, it is the name of the earth goddess and the universal mother, who takes her epithet from the Ancient Greek word for land or ground. It was this ecological element that led actress Emma Thompson to choose it for her daughter back in 1999, and it could hold similar appeal to green minded parents today.

Cressida is a pretty mythological and Shakespearean heroine name much better known in Britain than it is in the US. Given to just 7 girls in a recent year, it shares the cool golden meaning of Aurelia, Orla, and Goldie, and offers cute Cassie- alternative nickname Cressie, along with Ida and Sid too.

In Greek myth, Circe, daughter of Helios, the sun, was a sorceress living on the island of Aeaea, who could turn men into animals with her magic wand, which is just what she did to Odysseus's crew in Homer's Odyssey, transforming them into swine. All was forgiven, however, as Circe and Odysseus later had a child together—Telegonus.

Aura is a New Age-y word turned name turned contemporary slang for being cool, confident, and suave. Also associated with ancient mythology, the spiritual "essence" surrounding someone, with the atmosphere, light, or vibe something gives off, and with an oncoming migraine, Aura has a lot going for it — and against it too.

Doris had long been on our so-far-out-it-will-always-be-out-for-babies list, and seemed to be written there in indelible ink. But there are signs of a sea change, that Doris could profit from the revivals of Dorothy and Dorothea.

Like Violet, Lavender and Lilac, Ianthe is a purple flower name. Chosen by the poet Shelley for his daughter, Ianthe has a poetic, romantic, almost ethereal quality. In the ancient myth, she was the daughter of Oceanus, supreme ruler of the sea, and also a Cretan woman so beautiful that when she died the Gods made purple flowers grow around her grave.

Astraea —also found as Astraia — is the Greek goddess of justice and innocence who left earth to become the constellation Virgo after she grew unhappy with the state of humanity. She was prophesised to return and begin a new Golden Age, meaning she is associated with renewal — and with Queen Elizabeth I of England thanks to Renaissance writers associating her with the goddess.

Pandora has occasionally been used by the British gentry (for girls with brothers who might be called Peregrine) and is now starting to be heard in the US too: It was given to 34 baby girls last year.
