It will also be seen as we proceed, although the Earls of Ross were superiors of the lands of Kintail as part of the earldom, and that it was therefore impossible that Colin Fitzgerald or any other person than those earls could have had a gift of it from the Crown, that the Mackenzies occupied the lands and the castle, not as immediate vassals; of the King, but of their own near relatives, the O'Beolan Earls of Ross and their successors, for at least two hundred years before the Mackenzies received a grant of it for themselves direct from the Crown. This is proved beyond dispute by genuine historical documents. Until within a few years of the final forfeiture of the Lords of the Isles in 1476, the Mackenzies undoubtedly held their lands, first from the O'Beolan Earls and subsequently from the Island Lords as Earls of Ross; for the first direct Crown charter to any chief of Kintail of which we have authentic record, is one dated the 7th of January, 1463, in favour of Alexander "Ionraic," the sixth Baron. To show the intimate relations which existed between the original Earls of Ross and the ancestor of the Mackenzies, a quotation may be given from a manuscript history of the clan written by Dr George Mackenzie, nephew of Kenneth Mor, third Earl of Seaforth, in the seventeenth century. Although he is a supporter of the Fitzgerald origin, he is forced to say that, "at the same time (1267) William, Earl of Ross, laying a claim of superiority over the Western Isles, thought this a fit opportunity to seize the Castle of Ellandonnan. He sent a messenger to his Kintail men to send their young chieftain to him as being his nearest kinsman by marriage with his aunt." He then goes on to say, that Kenneth, not Colin, was joined by the MacIvers, Macaulays, MacBeolans, and Clan Tarlichs, "the ancient inhabitants of Kintail," and refused to surrender, when "the Earl of Ross attacked them and was beaten." Had there been no previous kinship between the two families - and no one will now attempt with any show of reason to maintain that there was not - this marriage of William, the second Earl, to Kenneth's aunt would have made the youthful Kenneth, ancestor of the Mackenzies, first cousin, on the maternal side, to William O'Beolan, the third Earl of that line, whose wife and therefore Kintail's aunt, was Joan, sister of John, the Black Comyn, Lord of Badenoch. It has further been proved to a demonstration, and it is now admitted by all the best authorities, that the O'Beolan Earls of Ross were descended from Gilleoin na h' Airde; and so are the Mackenzies, who from the first formed an integral and most important part of the ancient powerful native Gaelic tribes of which the Earls of Ross were the chiefs.
