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.”

Máire

“The Irish form of Mary, from the Latin "Maria" and Hebrew "Miryam", of debated meaning — possibly "sea of bitterness", "rebelliousness", or "their beloved". Máire is distinct from the English Mary in its Irish Gaelic form and was deliberately avoided as a given name in early Christian Ireland out of reverence for the Virgin Mary, which paradoxically led to it becoming one of the most common Irish women's names once that tradition relaxed in the post-medieval period.”

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.”

Aiden

“An anglicised spelling of Aodhán, the diminutive of the Old Irish Aodh, meaning "fire" — Aodh was the Celtic god of sun and fire. The name was borne by several early Irish saints, most notably Saint Aidan of Lindisfarne (c. 590–651), who helped Christianise northern England. Aiden is the most common American English spelling; Aidan is the Irish and British form.”

Paddy

“An informal diminutive of Patrick or Pádraig, from the Latin "Patricius" meaning "nobleman" or "patrician". Paddy is the traditional Irish nickname for Patrick, inseparably linked to Saint Patrick (c. 385–461 AD), the Romano-British missionary who converted Ireland to Christianity and whose feast day on 17 March is the national holiday of Ireland. Despite being used pejoratively in the past, Paddy remains a deeply affectionate Irish diminutive.”

Éabha

“The Irish form of Eve, from the Hebrew "Chavah" meaning "living" or "life-giver". In Irish Gaelic the name takes the form Éabha, pronounced quite differently from the English Eve, and has been used in Ireland since the early Christian period. In Irish tradition Éabha (Eve) is also associated with various legendary and mythological figures, and the name enjoyed a significant revival in Ireland during the twentieth-century Gaelic language revival.”

Siobhan

“The Irish form of Joan or Jane, introduced into Ireland via the Norman French name Jehanne during the medieval period. The name ultimately derives from the Hebrew Yohanan, meaning "God is gracious". Siobhán has been a staple of Irish feminine naming for centuries and became internationally recognisable through Irish actresses and cultural figures.”
