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.”

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

Aodhán

“A diminutive of Aodh, the Old Irish name for the god of fire (later Anglicised as Hugh). Aodhán means "little fire" and was an extremely common name in early medieval Ireland — Saint Aodhán of Ferns (Aidan of Lindisfarne in the Northumbrian tradition) was a 7th-century Irish monk who founded the famous monastery on Lindisfarne, carrying Celtic Christianity into England. The diminutive form gives it warmth and approachability while retaining the fire quality.”

Conn

“Derived from the Old Irish "conn" meaning "chief", "reason", "intelligence", or "head" — the same root that gives the modern Irish "ceann" (head). Conn of the Hundred Battles was one of the legendary High Kings of Ireland, ancestor of the Connachta dynasty, and the name was borne by numerous historical and legendary Irish rulers. It projects both intellectual authority and natural leadership.”

Doireann

“Derived from the Old Irish "doire" meaning "oak grove" (a sacred space in Celtic tradition) combined with a suffix — giving the meaning "daughter of the oak grove" or "she of the sacred grove". The oak was the most sacred tree in Celtic religion, associated with druids and the divine, making this name deeply rooted in pre-Christian Irish spirituality.”

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.”

Fergus

“Derived from the Old Irish elements "fer" meaning "man" and "guss" meaning "vigour", "strength", or "force" — together meaning "man of vigour" or "strong man". The name was borne by several early rulers of Ireland and Dál Riata, and most notably by the hero Fergus mac Róich of the Ulster Cycle, a warrior of extraordinary physical power and loyal character.”

Granuaile

“The Old Irish form of Grace, from "Gráinne" (itself possibly related to "grán", grain or sun) combined with the epithet "Mhaol" (bald, or of the cropped hair). Granuaile (Grace O'Malley, c. 1530–1603) was the legendary Irish chieftain and pirate queen of Connacht who commanded a fleet of ships, led her clan in armed rebellion against English expansion, and famously negotiated face-to-face with Queen Elizabeth I. She became one of the most celebrated figures in Irish folk memory.”
