Character Name

Diarmait

Meaning — The original Old Irish spelling of Diarmuid, from elements possibly meaning "without envy" from "di" (without) and "airmit" (jealousy or envy). Diarmait mac Cerbaill was the last High King of Ireland to hold the ancient pagan ceremony of the "Feis Temro" (Feast of Tara) around 560 AD. The name appears across Irish history and mythology and reflects the older, more austere orthographic tradition.·Old Irish origin·Male·DEER-mit

Diarmait Diarmait in its older spelling projects the archaic authority of the early Irish kingdom — a name for characters deeply embedded in the pre-Norman Gaelic world, defined by an older code of honour and a fiercer, less mediated relationship with the land and its gods. Characters named Diarmait tend to be formidably masculine in the old heroic manner, passionate and loyal with an intensity that admits no half-measures.

More Old Irish names

Brigid

Derived from the Old Irish "Brigit" or "Bríg", meaning "exalted one" or "the high one", from a Proto-Celtic root "briganti" meaning "high, lofty, the exalted one". Brigid was one of the most important goddesses of pre-Christian Ireland, associated with poetry, healing, smithcraft, and the hearth fire. The Christianised Saint Brigid of Kildare (c. 451–525) became one of Ireland's three patron saints.

Maeve

Anglicised form of the Irish "Méabh" or "Medb", possibly derived from an Old Irish word meaning "intoxicating" or "she who intoxicates" — connected to "mead" in its associations with sovereignty rituals. Queen Medb of Connacht is one of the most powerful figures in Irish mythology, the warrior queen whose desire for equal status with her husband triggers the great war of the Táin Bó Cúailnge.

Conchobar

From the Old Irish "Conchobar" (anglicised as Conor, Connor, or Cornelius), possibly meaning "lover of hounds" (from "con", hound/dog) or "high will" (from "con-", intensive prefix, and "cobor", desiring). In Irish mythology, Conchobar mac Nessa was the legendary King of Ulster and patron of the Red Branch Knights, presiding over the great warriors of the Ulster Cycle including Cúchulainn — one of the most complex and morally ambiguous kings in the Irish tradition.

Donal

From the Old Irish "Domhnall", composed of the Celtic elements "dubno" (world) and "val" (rule), meaning "ruler of the world". This was an extremely common name among Irish and Scottish kings and chieftains — multiple High Kings of Ireland bore the name, as did numerous Scottish monarchs and clan chiefs. The name projects both worldly authority and a specifically Celtic conception of kingship as stewardship of the land.

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).

The Children of Lir is one of the Three Sorrows of Irish Storytelling.
