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".

Éamon

The Irish form of Edmund, from the Old English "Ēadmund" meaning "wealthy protector" or "guardian of riches", from "ēad" (wealth, fortune) and "mund" (protector, guardian). The name entered Ireland through the Norman conquest and became fully naturalised in Irish Gaelic form. It is most famously borne by Éamon de Valera (1882–1975), the dominant figure of twentieth-century Irish politics, who served as both Taoiseach and President of Ireland.

Dessie

Dessie is an English masculine given name, most commonly a short form of Desmond, which derives from the Irish Deas-Mhumhan meaning "south Munster" — a territorial name from the Irish province. It may also be used as a feminine diminutive of Désirée (from the French for "desired"). The name is found primarily in Ireland, England, and the American South.

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.

Mairéad

The Irish form of Margaret, from the Greek "Margarites" meaning "pearl". Mairéad is the native Irish-language version of the name, distinct from the borrowed anglicised "Margaret" and carrying a distinctly Irish-Gaelic identity. The name has been borne by Mairéad Corrigan Maguire, the Northern Irish peace activist who co-founded the Community of Peace People and was awarded the Nobel Peace Prize in 1976.

Brennan

An Anglicised form of the Irish surname Ó Braonáin, meaning "descendant of Braonán", where Braonán is a diminutive of "braon" meaning "moisture", "drop", or "sorrow". The name is associated with Saint Brendan the Navigator (Naomh Bréanainn), the 6th-century Irish monk who, according to legend, sailed across the Atlantic to discover a western paradise. When used as a first name, it carries both the sorrow-drop etymology and the adventuring saint.

Kiera

An anglicised variant of the Irish "Ciarán" or the feminine "Ciara", from the Old Irish "ciar" meaning "dark", "black", or "dark-haired". Kiera represents the anglicised spelling used most commonly in the Irish diaspora, particularly in North America, where it gained prominence through Irish-American communities and the actress Keira Knightley (an alternative spelling).
