Nimue (Lady of the Lake) is the ruler of Avalon in the Arthurian legend. Nimue plays a pivotal role in many stories, including giving King Arthur his sword Excalibur, enchanting Merlin, and raising Lancelot after the death of his father.

This name of a Roman emperor and of a sedating plant is still used quietly, given to about a dozen baby boys in the US last year. It has a strong, rhythmic sound and could make a modern-feeling honor name for grandma Valerie.

Wolfgang Amadeus Mozart's middle name could make an interesting pick for music-loving parents--if only in middle place. Amadeus is the title of a Peter Shaffer play which became an award-winning film in 1984.

Seraphine is the Gallic version of the angelic name Seraphina. But while Seraphina has been rising rapidly since Jennifer Garner and Ben Affleck chose it for their second daughter, Seraphine has been largely ignored, though we believe the French vowel-sound ending will soon be more stylish than the a-endings that have predominated in girls' names for years.

Long more associated with the New York Waldorf- hotel and the neighborhood in Queens than as a baby name, Astoria is finally beginning to emerge from their shadow and find favor with parents looking to move beyond Brooklyn. The name Astoria is drawn from the surname of titan of industry John Jacob Astor, theorized to mean "hawk."

Artemis, one of the key figures of the female Greek pantheon, is the ancient virgin goddess of the hunt, wilderness, animals, childbirth, and a protector of young girls, later associated with the moon. Artemis is the equivalent to the Roman Diana, but a fresher and more distinctive, if offbeat, choice.

Acacius is a Latinized form of the Ancient Greek Akakios and can be interpreted to relate to the same root as the name Acacia, for the thorn bush, or Akakios which means "not evil." With the modern taste for ancient names that end in "us," this obscure but attractive choice may have a chance of new life. Acacius is the name of three early saints.

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.

A literary name created by J. R. R. Tolkien for a Lord of the Rings noblewoman of Rohan. Properly spelled with an accent over the first E – Éowyn – it would make an interesting choice for literature lovers or fans of names like Elowen and Evelyn.

The name of the Greek goddess of love has rarely descended to mortal use, though the Roman equivalent Venus, thanks to tennis star Williams, now seems completely possible. But with the new fashion for goddess names, we may see more little Aphrodites in the playground with Jupiter and Juno. Nineteen baby girls received the name in the US last year.

Officially a shortening of the traditional and tricky Gaelic Fionnghuala/Fionnuala, Nuala makes a lovely choice all on its own. Nuala is well-used in Ireland.

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

A modern, unisex Welsh name with a shiny feel, Eirian can mean "silver" (from Welsh arian) or "snow, brilliant, bright" (from eira). It may appeal to those who like rising star Eira, but want something longer, or more gender neutral.

Said to refer to either Jupiter or Venus, either of which would be preferable as a name.

A rarely heard--even in France--name, most prominent as the third name of Charlotte Marie Pomeline Casiraghi, the daughter of Princess Caroline of Monaco and granddaughter of Grace Kelly.

Sister of Antigone and daughter of Oedipus in Greek mythology, Ismene's name is unlikely to make it in modern times because of its teasability factor. Ismay or Esme would be better bets.

The name of a mythically handsome youth – loved by Selene, the moon, who bore him fifty daughters. If you're looking for a mythological name for your son, this might make an excellent choice both rare and appealing.

Rarely heard outside of Wales, Arianwen combines the pretty Welsh element gwen with the silvery arian, giving it a metallic and shining meaning. The name is sometimes listed as one of the daughters of the legendary fifth-century king and saint, Brychan Brycheiniog.

The least used of the Three Wise Men's names, but a strong option for bold namers to consider.

Since Morgan is used as--or more--frequently for girls as for boys, this feminization has fallen by the wayside. It drew some brief attention via the pop singer Morgana King.

The similar Morgiana appears in Tales from the Thousand and One Nights.
