Throughout this time, the descendants of the Cenél Loairn retained their identity; they were now the MacLeans. Now that John MacDonald was exiled, James IV restored the authority of the MacLeans over Mull. An earlier chief of the MacLeans had married the daughter of the first Lord of the Isles and received Duart Castle as the dowry; this now became the stronghold of MacLean control of Mull. The cadet branch of the family constructed a tower house at Moy on the southern side of Mull, while the senior branch retained Duart Castle.
