Macbeth certainly survived the English
invasion, for he was defeated and mortally wounded or killed by
the future Malcolm III ("King Malcolm Ceann-mor", son of
Duncan I) on the north side of the Mounth in 1057, after
retreating with his men over the Cairnamounth Pass to take his
last stand at the battle at Lumphanan. The Prophecy of
Berchán has it that he was wounded and died at Scone, sixty
miles to the south, some days later. Macbeth's stepson Lulach
mac Gille Coemgáin was installed as king soon after.
Unlike later writers, no near contemporary source remarks on
Macbeth as a tyrant. The Duan Albanach, which survives in
a form dating to the reign of Malcolm III, calls him "Mac Bethad
the renowned". The Prophecy of Berchán, a verse history
which purports to be a prophecy, describes him as "the generous
king of Fortriu", and says:
The red, tall, golden-haired one, he will be pleasant to me among them; Scotland will be brimful west and east during the reign of the furious red one.

line to descend from Kenneth MacAlpine, who united the Scots and Picts in 843
A.D. and is considered the founder of Scotland. One of Malcolm's three daughters, Bethoc,
married Crinan, the secular hereditary Abbot of Dunkeld. Through her, the Abbot's son
[Duncan] was installed by Malcolm as the King of Cumbria in 1018. After Malcolm II's
murder by his nobles at Glamis, Duncan killed his opponents and seized the throne as King
Duncan I. His first cousins, Macbeth (of Shakespearian fame) and Thorfinn the Raven
Feeder, Norwegian Earl of Orkney, united to advance MacBeth's claim to the throne through
his mother, another daughter of Malcolm II. Duncan reigned from 1034 until he was defeated
in battle by their combined armies and killed by MacBeth in August 1040 at Elgin. Scotland
was then ruled by Thorfinn in the northern districts and MacBeth in the southern
districts. -- James E. Fargo, FSA Scot., Clan Donnachaidh History.
