Character Name

Fionnán

Meaning — Diminutive of Fionn, from Old Irish "fionn" (white, fair, blessed) with the suffix "-án" indicating smallness or affection — "little fair one" or "dear fair one". Saint Fionnán (also Finán) of Kinnitty was an Irish monastic saint. The diminutive form gives it a warmth and approachability that the full Fionn lacks, suggesting someone whose brightness invites rather than overawes.·Old Irish origin·Male·FYUN-awn

Fionnán Fionnán has the warmth of Fionn made more intimate — the beloved fair one rather than the legendary hero. Characters with this name are often depicted as genuinely good-natured and generous, without the mythological distance that can make pure hero-names feel inaccessible. The diminutive quality gives them a human scale that allows them to operate in realistic settings without requiring epic surroundings.

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.”


More Old Irish names

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.”

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.”

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.”

Rónán

“Derived from the Old Irish "rón" meaning "seal" combined with the diminutive suffix "-án" — giving the meaning "little seal" or "young seal". In Irish tradition, seals were often believed to be fallen angels or transformed humans (selkies), and the name carries overtones of the liminal space between the natural and supernatural worlds. Several Irish saints bore the name.”

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.”

Dónall

“From the Old Irish "Domhnall" or "Dónall", composed of the Celtic elements "dubno" (world, deep) and "val" (rule), meaning "world ruler" or "mighty ruler of the world". The name was enormously popular in early Ireland — borne by numerous kings, warriors, and saints — and spread across the Celtic world as "Donald" in Scotland and "Dyfnwal" in Wales. It is one of the most ancient and historically attested Celtic masculine names.”
