Leda is at once simple, deeply-rooted, and unique: Only 23 baby girls were named Leda in the US last year. A name used in several European countries, pronunciation is usually the straightforward lee-dah but the Italians say lay-dah.

J.K. Rowling is a modern master of naming who brought a whole constellation of ancient and celestial names to modern parents. Bellatrix, of one of the stars of Orion, combines fashionable names Bella and Beatrix to make a convivial and original name. The down side: the Harry Potter character Bellatrix, played by Helena Bonham Carter, is a character so evil she's called a Death Eater, killing one beloved character and being murdered by another.

Adventurous parents are starting to look back to names of ancient gods like Mercury, Zeus, and Apollo. This one is also a planet and a metallic element, and has a friendly nickname, Merc.

Mercury is the planet associated with the sign of Virgo, so this is one of the prime names for Virgo babies.

Simple and yet distinctive, Ara is a mythological name of a famously handsome king. Although it originated as a boys' name, in the contemporary US, it's now much more commonly used for girls.

This name's meaning derives from the material from which the mythical sculptor Pygmalion chiselled his ideal woman - she was carved from ivory. Pygmalion fell in love with his creation and Aphrodite, taking pity on him, brought the sculpture to life. The woman was named Galatea due to her incredibly pale skin. The Pygmalion myth was the inspiration behind the story of "My Fair Lady" starring Julie Andrews on stage and Audrey Hepburn on screen.
