DONALD ([1060/65]-killed in battle 1085). There is no indication of the name of Donald's mother. His birth date is estimated on the assumption that he was an adult when killed, and old enough to have had a son himself at that time, but this precludes his being the son of Queen Margaret. It is possible that he was illegitimate. The Annals of Ulster record that "Domnall son of Mael Coluim, king of Scotland…ended [his] life unhappily" in 1085[285].

m ---. The name of Donald's wife is not known. Donald & his wife had [one possible child]:

a) [LADHMANN (-killed in battle 1116). The Annals of Ulster record that "Ladhmann son of Domnall, grandson of the king of Scotland, was killed by the men of Moray"[286]. It is not known with certainty to whom this refers, but a son of Donald, son of King Malcolm, is the most likely possibility.]
