Lasair

Meaning — 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.·Old Irish origin·Female·LAS-ir

More Old Irish names

Ruairi

Derived from the Old Irish "Ruaidhri" composed of "ruadh" meaning "red" or "red-haired" and "rí" meaning "king" — together meaning "red king" or "red-haired king". The name was popular among Irish and Scottish nobility. Ruaidrí Ua Conchobair (died 1198) was the last High King of Ireland before the Norman invasion, making the name historically resonant with the final era of Gaelic sovereignty.

Fionn

Derived from the Old Irish "find" meaning "white", "fair", or "fair-haired". It is one of the most celebrated names in Irish mythology as the given name of Fionn mac Cumhaill, the legendary leader of the Fianna warrior band. Fionn gained supernatural wisdom as a boy by accidentally tasting the Salmon of Knowledge, and he became Ireland's greatest hero and protector.

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.

Fionnuala

From the Old Irish "Fionn" (white, fair) and "guala" (shoulder), meaning "white-shouldered one" or "fair-shouldered one". In Irish mythology, Fionnuala was the eldest daughter of Lir, turned into a swan by her stepmother Aoife and forced to wander the waters of Ireland for nine hundred years. The tale of the Children of Lir is counted among the Three Sorrows of Irish Storytelling and is one of the most emotionally powerful myths in the Irish tradition.

Cáel

From the Old Irish "caol" meaning "slender" or "narrow". Cáel mac Crimthainn is a figure in the Fenian Cycle, a warrior of the Fianna and poet, celebrated for his beauty and for his tragic death on the same day as his beloved Créide. The poem "Créide's Lament for Cáel" is one of the finest short elegies in the Old Irish corpus. The name projects a refined, almost delicate masculine beauty.

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.
