Character Name

Aodhán

Meaning — 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.·Old Irish origin·Male·AY-dawn

Aodhán Aodhán projects fire in its domestic form rather than its conflagration mode — warmth, light, the fire that sustains rather than consumes. Characters with this name tend to be generous in spirit, energetic without being volatile, the person others gather around not for spectacle but for the reliable warmth they generate. The Aidan of Lindisfarne tradition adds a quality of missionary energy: taking what one knows and loves into unfamiliar territory.

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.

Seamus

Irish · “The Irish form of James, which derives from the Late Latin "Jacomus", a variant of "Jacobus", from the Hebrew "Ya'aqov" (Jacob) meaning "supplanter" or "he who follows at the heel". Séamus has been used in Ireland since the Norman introduction of the name James, and it has become one of the most recognisably Irish masculine names internationally, associated with Irish poetry, politics, and cultural identity.


More Old Irish names

Finn

An anglicised form of the Old Irish "Fionn", meaning "white", "fair", or "bright". The name is inseparable from the legendary figure of Fionn mac Cumhaill (Finn MacCool), the mythological hunter-warrior who led the Fianna — an elite band of warriors — whose exploits form the Fenian Cycle, one of the four great cycles of Irish mythology. According to legend, Finn gained supernatural wisdom by accidentally tasting the Salmon of Knowledge.

Aoibheann

Derived from the Old Irish "aoibh" meaning "beauty", "pleasantness", or "radiance", with the suffix "-eann" indicating a feminine bearer of that quality. Aoibheann is a traditional Irish name distinct from the shorter Aoibhinn, with a slightly more formal register. Several figures in Irish mythology bear this name, and it is associated with otherworldly beauty and gentleness.

Cliona

Possibly derived from Old Irish "clú" meaning "fame" or "renown" with a feminine suffix. Clíodhna (also spelled Clíona or Cliodhna) is a significant figure in Irish mythology — one of the three waves of Ireland and a queen of the sídhe (fairy mounds) of Munster. She was sometimes said to be the most beautiful woman in the world, ruling the otherworldly realm of Tír Tairngire.

Ita

Possibly derived from the Old Irish "íte" meaning "thirst" (in the spiritual sense, a thirst for God or goodness), or alternatively from a root meaning "honour" or "nobility". Saint Íte of Killeedy (died c. 570 AD) was one of the most important women in the early Irish Church, called "the foster-mother of the saints of Ireland" for her school in County Limerick that educated many monks.

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.

Eoghan

Possibly derived from the Old Irish form of the Greek "Eugenios" meaning "well-born" or "of good birth", or alternatively from a native Irish root related to "yew" or to "awin" (river). Eoghan was a popular name among Irish and Scottish royalty, borne by several early kings. Eòghann is the Scottish Gaelic form. The anglicised form Owen is common in Wales.
