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.”
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.”
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.”
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 Irish names
Branagh
“Derived from the Irish "Branach" meaning "descendant of Bran", with Bran meaning "raven". The name carries the raven symbolism of its root — prophecy, battle, and the boundary between life and death — while the "-ach" suffix gives it the sense of a person who embodies or descends from these qualities. The name is both a surname and given name in Irish tradition.”
Caitríona
“Irish form of Catherine or Katherine, derived from the Greek "Aikaterine" whose etymology is uncertain but may be connected to the Greek "katharos" meaning "pure". Caitríona is the specifically Irish Gaelic spelling distinguishing it from Catriona (Scottish Gaelic) and Catherine (English). It has been a consistently popular feminine name in Ireland and among the Irish diaspora.”
Clodagh
“Derived from the River Clóirtheach (anglicised as Clody) in County Wexford and County Carlow, Ireland. River names in Irish tradition often carry associations with flowing abundance, boundary-crossing, and the sacred nature of water. The name was popularised by the Marquess of Waterford, who named his daughter Clodagh in 1879, after which it entered the wider Irish naming tradition.”
Roisin
“Derived from the Irish word "rós" meaning "rose" combined with the diminutive suffix "-ín", giving the full meaning "little rose". The name carries deep cultural significance in Irish tradition through the poem "Róisín Dubh" (Dark Little Rose), a 16th-century allegorical poem in which Ireland is personified as a dark-haired girl — a coded political metaphor that persisted through centuries of occupation.”
Kellie
“Kellie is a feminine variant of Kelly, an Irish surname and given name derived from the Gaelic ceallach, possibly meaning "war" or "bright-headed." As a given name Kelly became popular in the English-speaking world from the mid-twentieth century, with Kellie as a distinctly feminine spelling variant.”
Breana
“A modern variant spelling of Brianna, the feminine form of Brian, an Irish name of disputed origin — likely from a Celtic root meaning "high," "noble," or "hill." The name Brian was borne by the legendary Irish High King Brian Boru (941–1014), which cemented its prestige in Irish tradition. Breana is the softer, more contemporary rendering of this lineage.”
