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.

Fionn
Old Irish · “Derived from the Old Irish "find" meaning "white", "fair", or "fair-haired". 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
Áine
“Derived from the Old Irish "áine" meaning "brightness", "radiance", or "splendour", possibly related to "áin" meaning "joy". Áine is a significant figure in Irish mythology — a goddess of summer, wealth, and sovereignty associated with the fairy mound of Knockainey in County Limerick. She was the queen of the Munster fairies and was closely connected with the sun and the ripening of crops.”
Lasair
“From the Old Irish "lasair" meaning "flame" or "blaze". Saint Lasair was a 6th-century Irish saint, daughter of the king of Connacht, whose feast day is celebrated in March. The name is strikingly evocative — flame as a feminine quality, the brightness that illuminates and warms but can also consume. It belongs to the tradition of Irish nature-names that describe a quality of being rather than a social role.”
Lochlainn
“Derived from the Old Irish "Lochlainn" meaning "land of the lochs" or "land of the lakes" — the Irish term for Scandinavia (later specifically Norway), the homeland of the Vikings who raided and settled Ireland from the 8th century. As a given name, it was adopted from the place name and came to carry associations with the Norse world and the Viking-Irish cultural fusion of medieval Ireland.”
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.”
Diarmait
“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.”
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.”
