 As a result, Domnall may have been the leading male representative of Echmarcach's family.The slaying of Domnall's brother, Amlaíb, as recorded by the "Annals of the Four Masters" in 1096, suggests that Domnall and the rest of the Meic Taidc faced significant opposition in the Isles, possibly in the form of Lǫgmaðr's adherents.The chronicle credits Domnall with an oppressive three-year reign that ended when the leading Islesmen revolted against him, and drove him from the kingdom back to Ireland.
