Burke's Peerage, page 1590, Cokayne's Complete Peerage XI-145: A recordof Sir David Graham, knight of Kincardine and Old Montrose, whoreportedly died 4 April 1373, lists a daughter Margaret, who marriedHugh, 6th Earl of Ross before 1329; however, it says her parentage isdoubtful. "Sir David was active in 1373, 44 years after Margaret's firstmarriage. That she was his daughter seems unlikely. This doubt isre-inforced by the exceptional number of generations in the lineagethrough Margaret between Elizabeth Keith and Sir David (9), as comparedwith 6 between Elizabeth Keith and Sir David going through Sir PatrickGraham." It would seem possible that Margaret was a
daughter of another David.
