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

Shane

An Ulster Irish anglicisation of Seán, itself the Irish form of John from the Hebrew Yohanan meaning "God is gracious". Shane was the form of the name used by the O'Neill clan of Ulster, most notably Seán an Díomais — "Shane the Proud" — Shane O'Neill (c. 1530–1567), the ferocious chieftain who dominated Ulster and defied both the English Crown and rival Irish clans, earning a reputation as one of the most unruly rulers in sixteenth-century Ireland.

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

The Irish form of John, introduced from the Norman French "Jean" (itself from Latin Iohannes and Hebrew Yohanan meaning "God is gracious") following the Norman invasion of Ireland in the twelfth century. Seán quickly displaced the older native form "Eoin" as the most common Irish masculine name and has remained so, producing some of the most celebrated names in Irish cultural history — from Seán O'Casey to Seán Lemass.

Reagan

An anglicised form of the Irish surname "Ó Riagáin" or "Ó Reagáin", derived from the Old Irish "riagán" possibly meaning "little king" or from "rí" (king) combined with a diminutive suffix. The name transitioned from a patronymic surname to a given name through the Irish-American tradition of using family surnames as first names, a practice that preserved ancestral Celtic identity through generations of the diaspora.

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.

Neil

Anglicised from the Irish Niall, a name of disputed meaning — proposed interpretations include "cloud," "passionate," "champion," and "vehement." The name was borne by several early Irish kings and saints, including Niall of the Nine Hostages, the legendary ancestor of the Uí Néill dynasty. Neil is the standard anglicised spelling used outside Ireland.
