* Son of Roland, Lord of Galloway. Roland, Lord of Galloway, married Ela or Helen de Moreville, sister of William de Moreville,High Constable of Scotland. The office of High Constable was hereditary in the family of the De Morevilles, and on the death of William, in 1196, went to Roland, in right of his wife; and then upon Alan's death, to her eldest grand-daughter Helena, and from her to the husbands of her daughters Margaret ard Elizabeth. Helena de Quincy's portion seems to have consisted of the estates and honors of the de Morevilles, whilst Galloway was reserved for the family of Margaret, of Scotland, the second wife of Alan.
† Shaw's History of Province of Moray. See Note 66 supra. The Galloway estates which were large, possessed by the Red Comyn, seem to have come to the family through this lady.

§ William Comyn, Earl of Buchan, put down the rebellion of Gillespoc, Earl of Moray, about 1229; and Alexander the Second gave him as a reward, the territory of Badenoch, for his second son Walter: who, on his death, passed it on to the next second son of the family, viz., John, the Black Comyn.-(See Appendix D.)
