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.

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.”

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.”

Aisling
“Derived from the Old Irish "aislinge" meaning "dream" or "vision". The word also refers to a specific genre of Irish poetry, the "aisling", in which Ireland is personified as a beautiful woman who appears in a vision and laments the country's oppression. The name thus carries rich literary and political associations, with overtones of visionary idealism and the pursuit of an Ireland not yet achieved.”
Nessa
“Of uncertain Old Irish etymology, possibly related to "ness" meaning "rough" or "wild". In the Ulster Cycle, Nessa was the mother of King Conchobar mac Nessa — his name means literally "son of Nessa" — a woman of great political cunning who manipulated the hero Fergus mac Róich into surrendering his kingship to her son by agreeing to marry Fergus only on condition he let Conchobar reign for a year.”
Eithne
“Derived from the Old Irish "eithne" meaning "kernel" or "grain nucleus" — the innermost, most essential part of a nut or seed. The name carries connotations of concentrated essence and inner worth. Eithne was a popular name in early medieval Ireland, borne by several queens and saints, and appears frequently in genealogies of Irish nobility.”
Conan
“Derived from the Old Irish "cú" (hound, warrior) or from a root meaning "high" or "chief" — giving possible meanings of "little warrior" or "little high one". Conan mac Morna was a figure in the Fenian Cycle, a member of the Fianna known for his sharp tongue and comic boastfulness. The name also has Breton connections through Saint Conan and a lineage of Breton/Cornish rulers.”
Orla
“Anglicised form of the Irish "Orfhlaith" (also spelled Orlaith), meaning "golden princess" or "golden sovereign", from the Old Irish "ór" (gold) and "flaith" (sovereignty, princess). The name was borne by several early Irish noblewomen, including a sister of Brian Boru — the High King of Ireland who defeated the Vikings at the Battle of Clontarf in 1014.”
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.”
