It was Máel Coluim III, not his father Donnchad, who did more to create the dynasty that ruled Scotland for the following two centuries. Part of the resource was the large number of children he had, perhaps as many as a dozen, through marriage to the widow or daughter of Thorfinn Sigurdsson and afterwards to the Anglo-Hungarian princess Margaret, granddaughter of Edmund Ironside. However, despite having a royal Anglo-Saxon wife, Máel Coluim spent much of his reign conducting slave raids against the English, adding to the woes of that people in the aftermath of the Norman Conquest of England and the Harrying of the North. Marianus Scotus narrates that "the Gaels and French devastated the English; and English were dispersed and died of hunger; and were compelled to eat human flesh".
