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.”
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.”
Ruairi
Old Irish · “Derived from the Old Irish "Ruaidhri" composed of "ruadh" meaning "red" or "red-haired" and "rí" meaning "king" — together meaning "red king" or "red-haired king". The name was popular among Irish and Scottish nobility. Ruaidrí Ua Conchobair (died 1198) was the last High King of Ireland before the Norman invasion, making the name historically resonant with the final era of Gaelic sovereignty.”

Aodhán
“A diminutive of Aodh, the Old Irish name for the god of fire (later Anglicised as Hugh). Aodhán means "little fire" and was an extremely common name in early medieval Ireland — Saint Aodhán of Ferns (Aidan of Lindisfarne in the Northumbrian tradition) was a 7th-century Irish monk who founded the famous monastery on Lindisfarne, carrying Celtic Christianity into England. The diminutive form gives it warmth and approachability while retaining the fire quality.”
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.”
Conn
“Derived from the Old Irish "conn" meaning "chief", "reason", "intelligence", or "head" — the same root that gives the modern Irish "ceann" (head). Conn of the Hundred Battles was one of the legendary High Kings of Ireland, ancestor of the Connachta dynasty, and the name was borne by numerous historical and legendary Irish rulers. It projects both intellectual authority and natural leadership.”
Emer
“Possibly derived from Old Irish elements meaning "swift" or related to the Proto-Celtic root for strength or readiness. Emer (also spelled Éimear) is the wife of the hero Cú Chulainn in the Ulster Cycle — but unlike most mythological wives, she is no passive figure. She is renowned for possessing all six gifts of womanhood: beauty, voice, sweet speech, needlework, wisdom, and chastity. She also successfully argues her case against a goddess for the right to her husband's love.”
Scáthach
“From the Old Irish "scáth" meaning "shadow" or "shade", with the suffix "-ach" indicating a bearer of that quality. Scáthach is one of the most fascinating figures in Irish mythology — a warrior woman and supernatural teacher who runs a school for heroes on the Isle of Skye (Dún Scáith). She trains Cú Chulainn in the arts of war and is portrayed as nearly omniscient in battle-craft. Her name, the Shadow, suggests someone who operates at the edge of the seen and known world.”
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.”
