Brion (Irish)
From Wikipedia, the free encyclopedia
Brion son of Eochaid Mugmedon, older half-brother of Niall Noigiallach (Niall of the Nine Hostages), was one of the three brothers whose descendants were known as the Connachta and who gave their name to the province of Connacht in the west of Ireland. His particular descendants, the Uí Briúin, gave rise to many Kings of Connacht and its ruling families over the next thousand years. A descendant of his via the Uí Briúin Ai was Tairrdelbach Ua Conchobair, who became High King of Ireland in 1166.
