At this time the first Earl William laid claim to the superiority of the Western Isles, which he and his father, Ferchair Mac an t'Sagairt; were chiefly instrumental, among the followers of Alexander III., in wresting from the Norwegians, and he was naturally desirous to have the government of Ellandonnan Castle in his own hands, or under the charge of some one less ambitious than Kenneth, and on whom he could implicitly rely. Kenneth was advancing rapidly both in power and influence among his more immediate neighbours, who were mainly composed of the ancient inhabitants of the district, the Mac Beolains, who occupied Glenshiel and the south side of Loch Duich as far as Kylerhea; the Mac Ivors, who inhabited Glen Lichd, the Cro of Kintail, and the north side of Loch Duich; while the Mac Tearlichs, now calling themselves Mac Erlichs or Charlesons, occupied Glenelchaig. These aboriginal natives naturally supported Kenneth, who was one of themselves, against the claims of his superior, the Earl, who though a pure Highland Celt was less known in Kintail than the Governor of the Castle. This only made the Earl more determined than ever to obtain possession of the stronghold, and he peremptorily requested the garrison to surrender it and Kenneth to him at once. The demand was promptly refused; and finding that the Governor was resolved to hold it at all hazards the Earl sent a strong detachment to take it by storm. Kenneth was readily joined by the surrounding tribes, among whom were, along with those whose names have been already given, the brave Macaulays of Lochbroom, who were distantly related to him. By the aid of these reinforcements Kenneth was able to withstand a desperate and gallant onset by the Earl and his followers, who were defeated and driven back with great slaughter. This exasperated the enemy so much that he soon after returned to the charge with a largely increased force, at the same time threatening the young governor with the utmost vengeance and final extirpation unless he immediately capitulated. But before the Earl was able to carry his threats into execution, be was overtaken by a severe illness of which he very soon after died, in 1274. His son, the second Earl William, did not persevere in his father's policy against Kintail, and it was not long before his attention was diverted into another channel. On the death of Alexander III., in 1286, the affairs of the nation became confused and distracted. This was rather an advantage to Kenneth than otherwise, for, in the general disorder which followed he was able to strengthen his position among the surrounding tribes. Through a combination of native prudence, personal popularity, and a growing power and influence heightened by the eclat of his having so recently defeated the powerful Earl of Ross, he succeeded in maintaining good order in his own district, while his increasing influence was felt over most of the Western Isles.
