Character Name

Oonagh

Meaning — 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.·Irish origin·Female·OO-na

Oonagh Oonagh carries the fairy queen's combination of supernatural beauty with sharp intelligence — she is not merely decorative but formidably clever, using wit where brute force would fail. The folk-tale tradition of Oonagh outwitting giants makes her ideal for characters who win through cunning rather than power. The name suits heroines who are underestimated precisely because of their golden beauty and feminine grace.

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.

Aisling

Old Irish · “Derived from the Old Irish "aislinge" meaning "dream" or "vision". The word also refers to a specific genre of Irish poetry, the "aisling", in which Ireland is personified as a beautiful woman who appears in a vision and laments the country's oppression. The name thus carries rich literary and political associations, with overtones of visionary idealism and the pursuit of an Ireland not yet achieved.

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.

Fionnuala

Old Irish · “Derived from the Old Irish "Fionnghala" composed of "fionn" meaning "white" or "fair" and "guala" meaning "shoulder" — together meaning "white shoulder" or "fair-shouldered". In the Irish legend of the Children of Lir, Fionnuala is the eldest daughter of the sea god Lir, transformed into a swan by her jealous stepmother Aoife and forced to wander the waters of Ireland for nine hundred years.


More Irish names

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.

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.

Keenan

An anglicised form of the Irish "Cianán" or "Caonán", diminutive forms meaning "little ancient one" (from "cian", ancient) or "little gentle one" (from "caon", gentle). The name was borne by several early Irish saints, including Saint Cianán of Duleek, who is credited with founding one of the earliest stone churches in Ireland at Duleek in County Meath in the fifth century.

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).

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.

Kevin

Anglicised from the Irish Caoimhín, composed of the Old Irish elements caomh ("dear, gentle, kind") and -gein ("birth"), meaning roughly "kind birth" or "beloved child." The name was popularised by Saint Kevin of Glendalough, a 6th-century Irish monk known for his asceticism and love of nature. Kevin became widely used in English-speaking countries in the 20th century.
