(b.c.1031 - d.1093) Scottish monarch. The son of King Duncan I (c.1010 - 1040), who was murdered by Macbeth. Malcolm took revenge by killing Macbeth and reclaiming the throne in 1057. He married twice; first to Ingiborg, widow of the Earl of Orkney (1059). Ingiborg having died, Malcolm married Margaret in 1069. She was a sister of Edgar the Atheling, who later became Saint Margaret. Malcolm was killed at Alnwick (Northumberland) during a raid on England in 1093, along with one of his sons. This news hastened the death of Margaret in Edinburgh Castle, who passed away only four days later. They lie buried together in Dunfermline Abbey. Canmore or Ceann-more is Gaelic meaning 'Great Head'. Four of Malcolm's sons succeeded to the throne of Scotland; Duncan II (c.1060 - 1094; reigning for only 6 months before being killed by his uncle), Edgar (c.1074 - 1107; reigned 1097 - 1107), Alexander I (c.1077 - 1124; reigned 1107-24), and David I (c.1080 - 1153; reigned 1124-53).
