Máel Coluim, Malcolm II, the High King of Scotland was the son of Kenneth II MacAlpin (Cináed mac Maíl Coluim) of Scotland, and grandson of Malcolm I (Máel Coluim mac Domnaill) of Scotland.
Malcolm's wife is unknown, he had no sons, and three daughters he married off strategically to men who could have been rivals:
* Bethoc, married to Crinan, Thane of the Isle
* Donada, married to Findlaich, Moraer of Moray
* Olith, married Sigurd, Earl of Orkney
Malcolm was known as a clever and ambitious man, and able to rule for twenty-nine years in an age when that was highly improbable. Much of his life is recorded in various medieval sources and authors, but most records leave much to speculation. Malcolm was killed at Glammys Castle fighting off bandits. Although the records vary, he most surely died by violence. His grandson by Bethoc, would be the next King of Scotland, and the basis for Shakespeare's King Duncan in the play, Macbeth (findagrave.com)
