In 1373 he received a grant of the North Isles, Garmoran, and other lands, to be held of  John, Lord of the Isles, and his heirs. His descendants comprehended the families of Moydart,  Morar, Knoydart, and Glengarry, and came in time to form the most numerous tribe of the  Clandonald, Alexander Macruari of Moydart, chief of the Clanranald, was one of the principal chiefs  seized by James I, at Inverness in 1427, and soon after beheaded. The great-grandson of Ranald, named Allan Macruari, who became chief of the Clanranald in 1481, was one of the principal supporters of Angus, the young Lord of the Isles, at the battle of Bloody Bay, and he likewise followed Alexander of Lochalsh, nephew of the Lord of the Isles, in his invasion of Ross and Cromarty in 1491, when he received a large portion of the booty taken on the occasion. In 1495, on the second expedition of James IV. to the Isles, Allan Macruari was one of the chiefs who made their submission. Ranald had five sons. Donald founded the Glengarry line. The eldest, Alan, became Chief of Clanranald. In 1419 Alan died in his home, the Castle of Tirrim. Roderick, a supporter of the Lord of the Isles, took his place as Chief and died in 1481.
