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.

The name was borne by several early rulers of Ireland and Dál Riata, and most notably by the hero Fergus mac Róich of the Ulster Cycle, a warrior of extraordinary physical power and loyal character.

More Old Irish names

Rónán

Derived from the Old Irish "rón" meaning "seal" combined with the diminutive suffix "-án" — giving the meaning "little seal" or "young seal". In Irish tradition, seals were often believed to be fallen angels or transformed humans (selkies), and the name carries overtones of the liminal space between the natural and supernatural worlds. Several Irish saints bore the name.

Fionnán

Diminutive of Fionn, from Old Irish "fionn" (white, fair, blessed) with the suffix "-án" indicating smallness or affection — "little fair one" or "dear fair one". Saint Fionnán (also Finán) of Kinnitty was an Irish monastic saint. The diminutive form gives it a warmth and approachability that the full Fionn lacks, suggesting someone whose brightness invites rather than overawes.

Bríd

The Old Irish form of Brigid, from the Proto-Celtic *Brigantī meaning "the exalted one" or "the high one". The name belongs to one of the most powerful figures in both Celtic paganism and Irish Christianity: the goddess Brigid, patroness of poetry, smithcraft, and healing, whose attributes were seamlessly absorbed by Saint Brigid of Kildare (c. 451–525 AD), co-patron saint of Ireland alongside Patrick and Columba.

Muireann

Derived from the Old Irish elements "muir" meaning "sea" and "fionn" meaning "white" or "fair" — together meaning "sea-white" or "fair one of the sea". The name has been used in Ireland since the early medieval period and appears in several Irish mythological tales. It has a maritime beauty that connects it to the Irish west coast and the deep significance of the sea in Irish cultural life.

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.

Crimthann

From the Old Irish "crimthann" meaning "fox". The fox in Celtic tradition represented cunning, adaptability, and the ability to survive through wit rather than strength. Several early Irish kings and saints bore this name, including Crimthann Mór mac Fidaig, a legendary king of Munster. The use of an animal name as a personal name is ancient in Irish tradition and projects a specific set of animal qualities onto the bearer.
