When the ablest upholders of the Colin Fitzgerald theory are obliged to make such admissions and explanations as these, they explain away their whole case and they must be held to have practically given it up; for once admit, as Sir William Fraser does, that the charter is of the reign of Alexander II. (1230), it cannot possibly have any reference to Colin Fitzgerald, who, according to those who support the Irish origin of the clan, only arrived in Scotland from Ireland in 1262 and it is equally absurd and impossible to maintain that a charter granted in 1230 could have been a reward for services rendered or valour displayed at the battle of Largs, which was fought in 1263, to say nothing of the now admittedly impossible date and signatures written on the face of the document itself; and Sir William Fraser having, by the logic of facts, been forced to give up that crucial point, should in consistency have at the same time given up Colin Fitzgerald. And in reality he practically did so, for having stated that the later reputed charters of 1360 and 1380 are not now known to exist, he adds, "But the terms of them as quoted in the early histories of the family are consistent with either theory of the origin of the Mackenzies, whether descended from Colin Fitzgerald or Colin of the Aird." In this he is quite correct; but it is impossible to say the same thing of the earlier charter, which all the authorities worth listening to now admit to be a palpable forgery of the seventeenth century; and Sir William virtually admits as much. There is one other fact which alone would be almost conclusive against the Fitzgerald theory. Not a single man of the name Colin is found, either among the chiefs or members of the clan from their first appearance in history until we come to Colin cam Mackenzie XI. of Kintail, who succeeded in June, 1568 - a period of three hundred years after the alleged date of the reputed charter to Colin Fitzgerald. Colin Cam was a second son, his eldest brother, Murdoch, having died during his father's life and before he attained majority, when Colin became heir to the estates. It was then, as now, a common custom to name the second son after some prominent member of his mother's family, and this was, no doubt, what was done in the case of Colin Cam, the first Colin who appears - as late as the middle of the sixteenth century - in the genealogy of the Mackenzies. His mother was Lady Elizabeth Stewart, daughter of John, Earl of Atholl, by Lady Mary Campbell, daughter of Archibald, second, and sister of Colin, third Earl of Argyll. Colin Cam Mackenzie, XI. of Kintail, and the first of the name in the family genealogy, was thus called Colin by his mother, Lady Elizabeth Stewart, after her uncle Colin, third Earl of Argyll.
