Dub Chablaigh ingen Cathal

Dubh Chablaigh was a daughter of King Cathal mac Conchobar mac Taidg of Connacht, who died in 1010. Her mother's identity is uncertain. Her brothers and half-brothers were Tadg in Eich Gil, Brian, Conchobor, In Cléirech, and Tadhg Díreach.

She was the fourth wife of Brian Boru and is thought to have been the mother of his son, Domnall, who died in 1010 or 1011. He was survived by a son, Diarmait, who died in 1051. Brian had three known daughters but it is unknown if Dub Chablaigh was the mother of any of them.

Brian styled himself Emperor of the Irish in 1005 at Armagh, which is the origin of her title.
