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.

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.

Catriona

Scottish Gaelic · “Scottish Gaelic form of Katherine or Catherine, derived from the Greek "Aikaterine", whose etymology is disputed but may relate to the Greek "katharos" meaning "pure". Catriona has been the distinctively Gaelic feminine form of the name in both Scotland and Ireland for centuries and was notably used by Robert Louis Stevenson as the title and heroine of his 1893 sequel to Kidnapped.


More Irish names

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.

Clodagh

Named after the River Clodagh in County Tipperary and County Waterford, Ireland — one of several Irish rivers whose names became given names. The river name itself is of uncertain Celtic origin, possibly derived from an ancient tribal or geographical term. Clodagh as a given name was popularised by the Marquess of Waterford who named his daughter after the family's local river in the late nineteenth century, making it a relatively modern addition to the Irish naming canon.

Caoimhe

Derived from the Irish word "caomh" meaning "gentle", "beautiful", or "precious". The name has been used in Ireland since the early medieval period and is associated with warmth, kindness, and quiet inner beauty. Several Irish saints bore forms of this name, reflecting its long tradition within Irish Christian culture.

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.

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.

Saoirse

From the Modern Irish "saoirse" meaning "freedom" or "liberty". Saoirse emerged as a given name in twentieth-century Ireland, part of a broader cultural movement to use Irish words of political and cultural significance as personal names. The name carries an obvious resonance with Irish nationalism and the struggle for independence, and has gained international recognition through the actress Saoirse Ronan.
