This is Child Ballad #183. Professor Child notes, "Two William MacIntoshes are Confounded in this ballad. The burning of Auchindown (sic)is attributed, rightly or wrongly, to an earlier William, captain of the clan, who, in August, 1550 was formally convicted of conspiracy against the life of the Earl of Huntly, then lietenant in the north, sentenced to lose his life and lands, and, despite a pledge to the contrary, executed shortly after by the Countess of Huntly."

Child's cited references are Lesley, John, History of Scotland; Gregory, Donald, History of the Western Highlands ed. 1881 and Browne, James, History of the Highlands, IV.
