Related names
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.”

Colleen
“From the Irish "cailín" meaning "girl" or "young woman". Uniquely among Irish names, Colleen originated not in Ireland but in the Irish diaspora of Australia and America, where English-speaking immigrants adopted the Irish word for "girl" as a given name. It was popularised through the theatrical phenomenon "The Colleen Bawn" (1860) by Dion Boucicault, the most performed play of the nineteenth century.”
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.”
Sinéad
“The Irish form of Jane or Janet, which are ultimately derived from the Hebrew "Yochanan" (Yahweh is gracious) via the Old French "Jehanne". Though ultimately of Hebrew origin, Sinéad is thoroughly and specifically Irish in character — it has been used in Ireland since the medieval period as the Irish equivalent of Jane and has been so completely naturalised that it functions as an authentically Irish name. Associated particularly with Irish music through singer Sinéad O'Connor.”
Seán
“Irish form of John, derived via the Old French "Jehan" from the Latin "Joannes" and Greek "Ioannes", ultimately from the Hebrew "Yohanan" meaning "God is gracious". Seán is one of the most common Irish masculine names and has been used in Ireland since the Norman period. Its anglicised form Shawn/Shane reflects the Irish pronunciation and is widely used throughout the English-speaking world.”
Éamon
“The Irish form of Edmund, from the Old English "Ēadmund" meaning "wealthy protector" or "guardian of riches", from "ēad" (wealth, fortune) and "mund" (protector, guardian). The name entered Ireland through the Norman conquest and became fully naturalised in Irish Gaelic form. It is most famously borne by Éamon de Valera (1882–1975), the dominant figure of twentieth-century Irish politics, who served as both Taoiseach and President of Ireland.”
Oonagh
“Possibly an Irish form connected to "Una" or "Oonagh", from Old Irish "uan" meaning "lamb" or possibly from a root meaning "unity" or "one". In Irish mythology and folklore, Áine/Oonagh appears as a fairy queen — Oonagh was the queen of the fairies in many folk traditions, the wife of Fionnbarra, king of the Irish fairies, renowned for her golden hair that reached the ground.”
