More Old Irish names

Íde

From the Old Irish "íde" possibly meaning "thirst" (for goodness or knowledge) or from an earlier root meaning "prosperity". Saint Íde (also Ita or Mide) of Killeedy was a 6th-century abbess and saint known as the "foster mother of the saints of Ireland", who according to legend fostered the young Saint Brendan and other monastic leaders. She is one of the most important female saints in the Irish tradition, whose monastic community in County Limerick became a centre of education and spiritual formation.

Maeve

Anglicised form of the Irish "Méabh" or "Medb", possibly derived from an Old Irish word meaning "intoxicating" or "she who intoxicates" — connected to "mead" in its associations with sovereignty rituals. Queen Medb of Connacht is one of the most powerful figures in Irish mythology, the warrior queen whose desire for equal status with her husband triggers the great war of the Táin Bó Cúailnge.

Dónall

From the Old Irish "Domhnall" or "Dónall", composed of the Celtic elements "dubno" (world, deep) and "val" (rule), meaning "world ruler" or "mighty ruler of the world". The name was enormously popular in early Ireland — borne by numerous kings, warriors, and saints — and spread across the Celtic world as "Donald" in Scotland and "Dyfnwal" in Wales. It is one of the most ancient and historically attested Celtic masculine names.

Conan

Derived from the Old Irish "cú" (hound, warrior) or from a root meaning "high" or "chief" — giving possible meanings of "little warrior" or "little high one". Conan mac Morna was a figure in the Fenian Cycle, a member of the Fianna known for his sharp tongue and comic boastfulness. The name also has Breton connections through Saint Conan and a lineage of Breton/Cornish rulers.

Sadhbh

From the Old Irish "sadb" meaning "sweet" or "goodly". In Irish mythology, Sadhbh is the mother of Oisín: she was transformed into a deer by the Dark Druid Fear Doirc and returned to human form when she entered the protection of Fionn mac Cumhaill. Their son Oisín ("little fawn") was born while she was again in deer form after she was recaptured. The name carries both gentleness and the tragedy of transformation.

Nuada

Derived from a Proto-Celtic root possibly related to "cloud" or "mist", or alternatively connected to an element meaning "to acquire" or "to catch". Nuada Airgetlám (Nuada of the Silver Hand) was the first king of the Tuatha Dé Danann in Irish mythology, who lost his hand at the First Battle of Mag Tuired and was temporarily deposed since a blemished king could not rule, until a silver prosthetic hand was crafted for him.
