Ceridwen

Welsh · “The etymology of Ceridwen is debated, but the most common interpretation draws on Welsh "cerdd" meaning "poetry" or "craft" and "gwen" meaning "white" or "blessed" — suggesting "blessed poetry" or "fair craftswoman". Another reading connects it to "creirwy" (a precious thing) and "gwen". In Welsh mythology she is the enchantress who brews the cauldron of poetic inspiration (the Awen) from which the bard Taliesin is born.”

Macha

Old Irish · “Possibly derived from the Old Irish "macha" related to a word for "plain" or "field", particularly the flat land around Armagh (Ard Macha — "Macha's height"). Macha is one of the triple aspects of the Morrígan in Irish mythology, a goddess of sovereignty, battle, horses, and fertility. Several figures named Macha appear in Irish mythology, all associated with the land of Ulster and the founding of Emain Macha.”

Nimue

Celtic · “The origin of Nimue is disputed; it may derive from Brythonic Celtic, possibly related to a word for "lake" or connected to the British water goddess Nemetona. Nimue is the Lady of the Lake in Arthurian legend — the enchantress who gives King Arthur his sword Excalibur, entraps the wizard Merlin in a cave or crystal tower, and raises Lancelot in her underwater realm. She is one of the most powerful female figures in the Matter of Britain.”

Sorcha

“Derived from the Old Irish word "sorcha" meaning "brightness", "radiance", or "light". It shares the same root as the modern Irish adjective "sorch" meaning "clear" or "bright". Sorcha has been used as an Irish equivalent of Sarah or Clara in anglicised contexts, though it is entirely distinct in origin. The name has been popular in Ireland and Scotland for centuries.”

Lír

“From the Old Irish "lir" meaning "sea" or possibly related to the Proto-Celtic sea deity. Lír (or Lir) was the Irish god of the sea and father of the four children who were transformed into swans in the most beloved of Irish mythological tales. The related figure Llyr appears in Welsh mythology in the Mabinogion, and scholars identify him with the legendary British king whose story Shakespeare transformed into King Lear.”

Nessa

“Of uncertain Old Irish etymology, possibly related to "ness" meaning "rough" or "wild". In the Ulster Cycle, Nessa was the mother of King Conchobar mac Nessa — his name means literally "son of Nessa" — a woman of great political cunning who manipulated the hero Fergus mac Róich into surrendering his kingship to her son by agreeing to marry Fergus only on condition he let Conchobar reign for a year.”

Ciara

“Derived from the Old Irish "ciar" meaning "dark", "black", or "dark-haired". Saint Ciara of Kilkeary was a sixth-century Irish saint, and the name appears throughout early Irish ecclesiastical records. The meaning reflects an older Celtic aesthetic that prized dark colouring, and the same root gives the male name Ciarán, meaning "little dark one".”

Declan

“Possibly derived from the Old Irish "Deaglán" or "Diaglán", with the most accepted interpretation being "full of goodness" or "man of prayer", though an alternate reading suggests "full of God" from "Dia" (God). Saint Declan of Ardmore was one of the earliest Christian missionaries in Ireland, predating Saint Patrick, and his name has been honoured in the Munster province for over fifteen centuries.”

Eimear

“Of Old Irish origin with uncertain etymology, possibly from "em" meaning "swift" or from a root related to "skill" or "craftsmanship". In Irish mythology, Eimear (also Emer) is the wife of Cúchulainn, chosen by him because she possessed the six gifts of womanhood: beauty, voice, sweet speech, wisdom, needlework, and chastity. She is one of the most fully realised female characters in Irish mythology.”
