Character Name

Declan

Meaning — 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.·Old Irish origin·Male·DEK-lan

Declan Declan projects quiet moral seriousness rooted in the Irish tradition of the holy man who is also a doer of practical good. The name suits characters who operate from a deep internal moral code rather than public performance of virtue, often serving as a stabilising force in turbulent narratives. Modern bearers of the name — including rock musicians and sportspeople — have given it a contemporary edge that blends tradition with irreverence.

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.

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.

Padraig

Irish · “The Irish form of Patrick, derived from the Latin "Patricius" meaning "nobleman" or "of noble birth", from "pater" (father). Saint Patrick (c. 385–461 AD), the patron saint of Ireland, was a Romano-British missionary who became the most celebrated figure in Irish Christianity. The Irish form Pádraig has been used in Ireland continuously since the early medieval period.


More Old Irish names

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.

Lír

From the Old Irish "lir" meaning "sea" or possibly related to the Proto-Celtic sea deity. Lír (or Lir) was the Irish god of the sea and father of the four children who were transformed into swans in the most beloved of Irish mythological tales. The related figure Llyr appears in Welsh mythology in the Mabinogion, and scholars identify him with the legendary British king whose story Shakespeare transformed into King Lear.

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.

Méabh

The older spelling form of Maeve, derived from Old Irish "medb" meaning "she who intoxicates" or "mead" — cognate with the drink associated with sovereignty. Méabh is the great warrior queen of Connacht in the Ulster Cycle, the driving force behind the Táin Bó Cúailnge (Cattle Raid of Cooley). She is one of the most powerful and complex female figures in all Celtic mythology — a queen who commands armies, takes and dismisses husbands at will, and matches her political authority with personal sovereignty.

Conchobar

From the Old Irish "Conchobar" (anglicised as Conor, Connor, or Cornelius), possibly meaning "lover of hounds" (from "con", hound/dog) or "high will" (from "con-", intensive prefix, and "cobor", desiring). In Irish mythology, Conchobar mac Nessa was the legendary King of Ulster and patron of the Red Branch Knights, presiding over the great warriors of the Ulster Cycle including Cúchulainn — one of the most complex and morally ambiguous kings in the Irish tradition.

Deirdre

The etymology is uncertain, but possible derivations include Old Irish "derdriu" meaning "sorrowful" or "broken-hearted", or alternatively related to a root meaning "wanderer" or "she who chatters". Deirdre is the tragic heroine of one of the Three Sorrows of Storytelling in Irish mythology — the tale of Deirdre of the Sorrows — whose beauty was prophesied to bring ruin to Ulster.
