Cillian
Old Irish · “Probably derived from the Old Irish "cell" meaning "church" combined with a diminutive suffix, giving the sense of "associated with the church" or "little church". The name was borne by the 7th-century Irish saint Killian of Würzburg, who evangelised in Franconia and was martyred there, spreading Irish Christianity across continental Europe.”
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.”
Declan
Old Irish · “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.”
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.”

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.”
Diarmuid
“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.”
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.”
Rónán
“From the Old Irish "rón" meaning "seal" combined with the diminutive suffix "-án", giving the meaning "little seal" or "seal-like one". In Irish mythology and folklore, seals were often considered to be transformed humans — the selkie tradition — and Rónán figures in several tragic Irish tales, most notably the tale of Rónán mac Aed, a king whose jealous son falsely accuses his stepmother, leading to a catastrophe reminiscent of the Greek myth of Phaedra and Hippolytus.”
Liadan
“From the Old Irish "líadan" meaning "grey lady" or "lady of the grey hair", from "lía" (grey) and the feminine suffix. Liadan is the protagonist of one of the most moving love stories in early Irish literature — the tale of Líadan and Cuirithir, two poets who fall in love but whose relationship is destroyed when Líadan takes holy vows, choosing religious devotion at the cost of human love. The surviving lament attributed to her is among the earliest and most beautiful poems in Old Irish.”
Niall
“An Old Irish name of debated etymology — most scholars derive it from a Proto-Celtic root meaning "champion", "cloud", or possibly "passionate". It is most famously borne by Niall of the Nine Hostages (Niall Noígíallach), the legendary High King of Ireland from around the 4th–5th century whose descendants, the Uí Néill dynasty, dominated Irish politics for centuries. Genetic studies suggest a remarkable proportion of men with Irish heritage descend from him.”
