Donnchad Donn

From Wikipedia, the free encyclopedia

Donnchad was married three times. His first wife was Cainnech (died 929), daughter of Canannán, King of the northern Uí Néill sept of the Cenél Conaill. His second wife was Órlaith, sister of Brian Boru of the Dál gCais. Órlaith was killed in 941, apparently on Donnchad's order, perhaps due to a sexual relationship between her and her stepson Óengus. Donnchad's third wife, Dublemna (died in 943, was the daughter of king of Bréifne.
