Character Name
Oisín
Oisín Oisín carries the dual heritage of the warrior and the poet — physically courageous yet deeply sensitive to beauty and loss. Characters with this name are often storytellers at heart, men who have witnessed great things and carry the weight of memory. The myth of Oisín returning from Tír na nÓg to find his world transformed gives the name a melancholy, elegiac quality perfect for characters out of step with their own era.

It is one of the most celebrated names in Irish mythology as the given name of Fionn mac Cumhaill, the legendary leader of the Fianna warrior band. Fionn gained supernatural wisdom as a boy by accidentally tasting the Salmon of Knowledge, and he became Ireland's greatest hero and protector.”
Fergus
Old Irish · “Derived from the Old Irish elements "fer" meaning "man" and "guss" meaning "vigour", "strength", or "force" — together meaning "man of vigour" or "strong man". 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.”
Diarmuid
Old Irish · “Derived from the Old Irish "Diarmait", possibly from "di" (without) and "airmit" (envy) — meaning "without envy" or "free from jealousy". Alternatively interpreted as "freeman". In Irish mythology, Diarmuid Ua Duibhne was the most handsome warrior of the Fianna, whose magical "love spot" on his forehead caused any woman who glimpsed it to fall instantly in love with him, leading to the legendary elopement with Gráinne.”
Cormac
Old Irish · “Derived from the Old Irish "corb" meaning "chariot" (or possibly "raven") and "mac" meaning "son" — giving the meaning "son of the chariot" or possibly "charioteer's son". The name was borne by the legendary High King Cormac mac Airt, considered one of Ireland's greatest and wisest kings, whose court at Tara became associated with an idealised golden age of justice and prosperity.”
Conor
Irish · “Anglicised form of the Irish "Conchobar" or "Conchobhar", derived from "con" (dog or wolf, used as an honorific for a great warrior) and "cobhar" (desiring or loving) — together possibly meaning "lover of hounds" or "wolf-lover". Conchobar mac Nessa was the king of Ulster in the Ulster Cycle of Irish mythology, the lord who ruled over the great warriors including Cúchulainn.”
More Old Irish names
Caoilfhinn
“Compound Old Irish name from "caol" (slender, narrow) and "fionn" (white, fair, blessed). The name combines physical grace with the light-filled beauty implied by "fionn". It is an authentically traditional Irish name that represents the layered compound structure common in early medieval Irish personal naming. Several saints and noblewomen in medieval Irish records bear this name.”
Aisling
“From the Old Irish "aisling" or "aislinge" meaning "dream" or "vision". In Irish literary tradition, an aisling is a specific genre of poem in which a poet encounters a beautiful woman in a dream — the personification of Ireland — who laments the country's suffering under foreign rule and prophecies its liberation. The name thus carries the weight of an entire literary and political tradition within Irish culture.”
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.”
Lugaid
“Derived from the Old Irish god-name Lugh, with the suffix "-aid" making it a personal name in the human sphere. Lugaid was an extremely common name in early medieval Ireland — several kings and mythological figures bear it, including Lugaid mac Con, Lugaid Riab nDerg (of the red stripes, a legendary High King), and Lugaid mac Maic Con. The name carries the solar brightness of Lugh into a human register.”
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.”
Muirenn
“From the Old Irish "muir" (sea) and "fionn" (white, fair, blessed), meaning "white sea" or "fair-haired one of the sea". Distinct from Muireann (which shares similar elements), Muirenn appears in Irish genealogical and mythological records. The sea element connects the name to the liminal world where Ireland meets the Atlantic, a geography that deeply shapes Irish imaginative culture.”
