King Duncan I King of Scotland^

  Noted events in his life were:

• Royal. c.1010 - 1040 Scottish monarch. Succeeded his maternal grandfather King Malcolm II (c.954 - 1018), which was much resented by MacBeth (c.1005 - 1057), who was also a grandson of Malcolm, and has expected to succeed him. Duncan could not have been different from Shakespeare's portrayal, he was foolhardy and not particularly effective. MacBeth formed an alliance with their cousin the Earl of Orkney, and they defeated and killed Duncan near Forres. Duncan's son Malcolm Canmore (c.1031-93) succeeded to the throne only after he had defeated MacBeth and MacBeth's son Luloch.

Duncan married Aeflaed of Northumbria.
