 The ecclesiastical jurisdiction of the Kingdom of the Isles, from the mid twelfth century at least, was the Diocese of the Isles.Little is known of the early history of the diocese, although its origins may well lie with the Uí Ímair "imperium".The episcopal succession of the Isles, as recorded in the "Chronicle of Mann", starts its chronology at about the time of the reign of Gofraid Crobán, King of Dublin and the Isles.
