 Whatever the case, the chronicle reveals that Ua Briain then installed Domnall mac Taidc upon the throne.Although Domnall had previously opposed Ua Briain over the kingship of Munster, he was the son of Ua Briain's brother, and further possessed strong familial connections with the Isles through his maternal descent from Echmarcach mac Ragnaill, King of Dublin and the Isles.In fact, the "Annals of Ulster" appears to indicate that at least two apparent members of Echmarcach's family were killed less than a decade before in a repulsed invasion of Mann.
