Niamh

Old Irish · “Derived from the Old Irish word "niamh" meaning "bright" or "radiant". The name belongs to one of the most celebrated figures of Irish mythology, Niamh of the Golden Hair, a princess of Tír na nÓg (the Land of Eternal Youth) who fell in love with the poet-warrior Oisín and carried him away on her white horse across the sea.”

Aoife

Old Irish · “Derived from the Old Irish "Aífe", itself from the word "oíph" meaning "beauty" (modern Irish "aoibh"). This ancient Irish name has been borne by several legendary figures, most notably a fierce warrior woman who engaged in single combat with the hero Cúchulainn, and a jealous queen in the tale of the Children of Lir who transformed her stepchildren into swans.”

Saoirse

Irish · “Derived directly from the Irish word "saoirse" meaning "freedom" or "liberty", itself from "saor" meaning "free". The name rose to prominence in Ireland during the 1920s, in the aftermath of the Irish War of Independence and the establishment of the Irish Free State, when the concept of freedom carried profound political and cultural weight.”

Brigid

Old Irish · “Derived from the Old Irish "Brigit" or "Bríg", meaning "exalted one" or "the high one", from a Proto-Celtic root "briganti" meaning "high, lofty, the exalted one". Brigid was one of the most important goddesses of pre-Christian Ireland, associated with poetry, healing, smithcraft, and the hearth fire. The Christianised Saint Brigid of Kildare (c. 451–525) became one of Ireland's three patron saints.”

Cliona

Old Irish · “Possibly derived from Old Irish "clú" meaning "fame" or "renown" with a feminine suffix. Clíodhna (also spelled Clíona or Cliodhna) is a significant figure in Irish mythology — one of the three waves of Ireland and a queen of the sídhe (fairy mounds) of Munster. She was sometimes said to be the most beautiful woman in the world, ruling the otherworldly realm of Tír Tairngire.”


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.”

Fearghal

“From the Old Irish "Fearghall" or "Fergal", composed of "fear" (man) and "gal" (valour, ferocity), meaning "man of valour" or "super-valour". The name was borne by Fergal mac Máele Dúin, King of Ireland from 710 to 722 AD, and by Saint Fergal (Virgilius) of Salzburg — an Irish monk who became Bishop of Salzburg and controversially taught that the Earth was spherical, centuries before it was widely accepted in Europe.”

Bríd

“The Old Irish form of Brigid, from the Proto-Celtic *Brigantī meaning "the exalted one" or "the high one". The name belongs to one of the most powerful figures in both Celtic paganism and Irish Christianity: the goddess Brigid, patroness of poetry, smithcraft, and healing, whose attributes were seamlessly absorbed by Saint Brigid of Kildare (c. 451–525 AD), co-patron saint of Ireland alongside Patrick and Columba.”

Ciara

“Derived from the Old Irish "ciar" meaning "dark", "black", or "dark-haired". Saint Ciara of Kilkeary was a sixth-century Irish saint, and the name appears throughout early Irish ecclesiastical records. The meaning reflects an older Celtic aesthetic that prized dark colouring, and the same root gives the male name Ciarán, meaning "little dark one".”

Muirgheal

“From the Old Irish "muir" (sea) and "geal" (bright, white), meaning "bright as the sea" or "bright sea". The name appears in early Irish sources and belongs to the tradition of Irish feminine names formed from natural imagery — particularly the sea, which held enormous symbolic importance in a country surrounded by it. It represents the feminine form of the "sea" name cluster alongside Muireann and Muirenn.”

Lasair

“From the Old Irish "lasair" meaning "flame" or "blaze". Saint Lasair was a 6th-century Irish saint, daughter of the king of Connacht, whose feast day is celebrated in March. The name is strikingly evocative — flame as a feminine quality, the brightness that illuminates and warms but can also consume. It belongs to the tradition of Irish nature-names that describe a quality of being rather than a social role.”
