Welsh and Celtic

Adira is one of those rare names that's both little-used and simple, and crosses languages easily. Pronounced ah-DEER-ah, Adira is given to only a handful of girls in the US each year and could make a worthy substitute for such overexposed favorites as Ava and Ariana.

Aoife, pronounced EE-fa, is derived from the Irish word aoibh, meaning "beauty." Aoife was borne by several different heroines of ancient Irish legend. In one tale, she was the fiercest woman warrior in the world and enemy of her twin sister, Scathach.

Spelling variant of Arianwen. Note that in Welsh, the -wyn suffix is usually masculine.

Unusual floral name which would be perfect for a spring baby girl, if you can pronounce the Welsh double L correctly. It's a tricky sound for non-native Welsh speakers, kind of halfway between an H and an L.

Celtic goddess of poetry, though less-than-poetic name.

If you like soft, lispy Welsh names like Gwyneth, consider this out-of-the-ordinary one.

Irish Gaelic form of Evelyn or Aveline, more authentically spelled Eibhlín.

Evanna is the name of a Harry Potter actress who pronounces it ee-vah-na. This might be considered yet another international feminine form of the many variations of John; Ivana, Giovanna, and even Joan are cousins of Evanna.

A strong, classic, simple name that has nonetheless never been overexposed.

Guinevere was the name of the beautiful but ill-fated queen of Camelot, for so many years eclipsed by its modern Cornish form Jennifer. Today, Guinevere could be a cool possibility for adventurous parents intrigued by this richly evocative and romantic choice.

Gwendolen, an ancient Welsh favorite, retired decades ago in favor of the short form Gwen, but now, as in the case all across the naming board, the nickname has faded and the more distinguished original is up for reappraisal.

Maeve is a short and sweet name that has become one of the most stylish Irish names for girls in the modern US. Maeve would make an excellent first or middle name choice, with more heft than Mae/May and more modern charm than Mavis.

Meredith is a soft, gentle-sounding name with subtle Welsh roots. Although originally a boys’ name , Meredith is used mainly for girls now.

Morwenna is an ancient Cornish name now being revived in Wales, deriving from a Celtic word meaning "maiden", although the Mor- syllable means that it's often associated with the sea. It's been heard in the British series Doc Martin and Poldark. Morwenna Banks is a British actress.
