In 1602, the old and long-standing feud between the Mackenzies and the Macdonalds of Glengarry, concerning their lands in Wester Ross, was renewed with infuriated violence. Ultimately, after great bloodshed and carnage on both sides, an arrangement was arrived at by which Glengarry renounced for ever, in favour of Mackenzie, the Castle of Strome and all his lands in Lochalsh, Lochcarron, and other places in the vicinity, so long the bone of contention between these powerful and ferocious chieftains. In 1607, a Crown charter for these lands was granted to Kenneth, thus materially adding to his previous possessions, power, and influence. “All the Highlands and Isles, from Ardnamurchan to Strathnaver, were either the Mackenzies’ property or under their vassalage, some few excepted,” and all around them were bound to them “by very strict bonds of friendship”. In this same year Kenneth received, through some influence at Court, a gift, under the Great Seal, of the Island of Lewis, in virtue of, and thus confirming, the resignation of this valuable and extensive property previously made in his favour by Torquil Macleod. A complaint was, however, made to his Majesty by those of the colonists who survived, and Mackenzie was again forced to resign it. By patent, dated the 19th of November, 1609, he was created a peer of the realm, as Lord Mackenzie of Kintail. Soon after, the colonists gave up all hopes of being able to colonize the Lewis, and the remaining adventurers—Sir George Hay and Sir James Spens—were easily prevailed upon to sell their rights to Lord Mackenzie, who at the same time succeeded in securing a grant from the king of that part of the island forfeited by Lord Balmerino, another of the adventurers. He (Lord Mackenzie) now secured a commission of fire and sword against the islanders, soon arrived with a strong force, and speedily reduced them to obedience, with the exception of Neil Macleod and a few of his followers. The struggle between these two continued for a time, but ultimately Mackenzie managed to obtain possession of the whole island, and it remained in the possession of the family until it was sold by the “Last of the Seaforths”.
