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.

Deirdre

Old Irish · “The etymology is uncertain, but possible derivations include Old Irish "derdriu" meaning "sorrowful" or "broken-hearted", or alternatively related to a root meaning "wanderer" or "she who chatters". Deirdre is the tragic heroine of one of the Three Sorrows of Storytelling in Irish mythology — the tale of Deirdre of the Sorrows — whose beauty was prophesied to bring ruin to Ulster.

Clodagh

Irish · “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.


More Old Irish names

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.

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".

Muirenn

From the Old Irish "muir" (sea) and "fionn" (white, fair, blessed), meaning "white sea" or "fair-haired one of the sea". Distinct from Muireann (which shares similar elements), Muirenn appears in Irish genealogical and mythological records. The sea element connects the name to the liminal world where Ireland meets the Atlantic, a geography that deeply shapes Irish imaginative culture.

Lir

From the Old Irish name Ler or Lir meaning "sea" or "ocean". Lir is the Irish sea god, cognate with the Welsh Llŷr (father of Brân the Blessed). His most famous appearance in Irish mythology is as the father in the Children of Lir, whose four children are transformed into swans by their jealous stepmother for nine hundred years. The Children of Lir is one of the Three Sorrows of Irish Storytelling.

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.

Lasairfhíona

Derived from the Old Irish elements "lasair" meaning "flame" and "fíon" meaning "wine" — together meaning "flame of wine" or "wine-bright flame". This is an ancient and rare Irish name suggesting the warm glow and intoxicating quality of wine and firelight combined. It was used in medieval Ireland as a poetic name for women of remarkable beauty and vivacity.
