The same authorities who affirm that Agnes of Argyll was Alexander's first wife assert that Anna Macdougall, was his second. There is ample testimony to show that the latter was his first, although some confusion has again arisen in this case from a similarity of names and patronymics. Some of the family MSS. say that Alexander's second wife was Margaret, daughter of "M'Couil," "M'Chouile," or "Macdougall" of Morir, or Morar, while others, among them the Allangrange Ancient MS. have it that she was "MacRanald's daughter." The Ardintoul MS. describes her as "Muidort's daughter." One of the Gairloch MSS. says that she was "Margarite, the daughter of Macdonald of Morar, of the Clan Ranald Race, from the stock of Donald, Lord of the Aebudae Islands," while in another MS. in Sir Kenneth Mackenzie's possession she is designated "Margaret Macdonald, daughter of Macdonald of Morar." There is thus an apparent contradiction, but it can be conclusively shown that the lady so variously described was one and the same person. Gregory in his Highlands and Islands of Scotland, p.158, states that "Macdougall" was the patronymic of one of the families of Clan Ranald of Moydart and Morar. Speaking of Dugald MacRanald, son and successor to Ranald Ban Ranaldson of Moydart, he says, "Allan the eldest son of Dougal, and the undoubted male heir of Clan Ranald, acquired the estate of Morar, which he transmitted to his descendants. He and his successors were always styled, in Gaelic, MacDhughail Mhorair, ie., MacDougal of Morar, from their ancestor, Dougald MacRanald." At p.65 he says that "the Clan Ranald of Garmoran comprehended the families of Moydart, Morar, Knoydart, and Glengarry." This family was descended from Ranald, younger son of John of the Isles, by his marriage with the heiress of the MacRorys or MacRuaries of Garmoran whose ancestry, from Somerled of the Isles, is as illustrious as that of any family in the kingdom. A district north of Arisaig is still known among the Western Islanders as "Mor-thir Mhic Dhughail" or the mainland possession of the son of Dougall. The MS. histories of the Mackenzies having been all written after the patronymic of "MacDhughail" was acquired by the Macdonalds of Moydart and Morar, they naturally enough described Alexander of Kintail's second wife as a daughter of Macdougall of Morar, of Muidort, and of Clan Ranald, indiscriminately. But in point of fact all these designations describe one and the same person. Alexander married first, Anna, daughter of John Macdougall of Dunolly, with issue - 1. Kenneth, his heir and successor. 2. Duncan, progenitor of the Mackenzies of Hilton, and their branches, and of whom in their order as the senior cadet family of the clan. He married secondly Margaret, daughter of Macdonald of Morar, a cadet of Clanranald, with issue - 3. Hector Roy or "Eachainn Ruadh," from whom are descended the Mackenzies of Gairloch and their various offshoots, of whom in their proper place.
