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 in 1059 to Ingiborg, widow of the Earl of Orkney. After Ingiborg's death, Malcolm married again in 1069 to Margaret, grand-daughter of King Edmund II (Ironside) of England and sister of Edgar the Atheling.
William the Conqueror captured the English throne in 1066. Malcolm resisted his march north into Scotland, but was eventually forced to accept William's superior force and paid homage to him at Abernethy in 1072. Malcolm sent his eldest son, Duncan, south as a hostage and many Norman knights remained in Scotland to protect the peace. The succeeding years brought periods of peace followed by opportunistic raids into England. Malcolm was killed at Alnwick (Northumberland) during one such raid 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).
