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.”

Eoin

“The Old Irish form of John, derived from the Latin Iohannes and ultimately from the Hebrew Yohanan meaning "God is gracious". Eoin entered Ireland through the early Christian Church and has remained in continuous use for over a thousand years. It is distinct from the later anglicised "Seán" (which came via Norman French) and is considered the more archaic, native form of the name in Irish.”

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".”

Lir

“From the Old Irish name Ler or Lir meaning "sea" or "ocean". Lir is the Irish sea god, cognate with the Welsh Llŷr (father of Brân the Blessed). His most famous appearance in Irish mythology is as the father in the Children of Lir, whose four children are transformed into swans by their jealous stepmother for nine hundred years. The Children of Lir is one of the Three Sorrows of Irish Storytelling.”

Finn

“An anglicised form of the Old Irish "Fionn", meaning "white", "fair", or "bright". The name is inseparable from the legendary figure of Fionn mac Cumhaill (Finn MacCool), the mythological hunter-warrior who led the Fianna — an elite band of warriors — whose exploits form the Fenian Cycle, one of the four great cycles of Irish mythology. According to legend, Finn gained supernatural wisdom by accidentally tasting the Salmon of Knowledge.”

Fionnuala

“Derived from the Old Irish "Fionnghala" composed of "fionn" meaning "white" or "fair" and "guala" meaning "shoulder" — together meaning "white shoulder" or "fair-shouldered". In the Irish legend of the Children of Lir, Fionnuala is the eldest daughter of the sea god Lir, transformed into a swan by her jealous stepmother Aoife and forced to wander the waters of Ireland for nine hundred years.”

Emer

“Possibly derived from Old Irish elements meaning "swift" or related to the Proto-Celtic root for strength or readiness. Emer (also spelled Éimear) is the wife of the hero Cú Chulainn in the Ulster Cycle — but unlike most mythological wives, she is no passive figure. She is renowned for possessing all six gifts of womanhood: beauty, voice, sweet speech, needlework, wisdom, and chastity. She also successfully argues her case against a goddess for the right to her husband's love.”
