death of the Mormaor she married Macbeth, and when Macbeth slew Duncan
(1040), he was removing a usurper--as he understood it--and he ruled in
the name of his stepson, Lulach. The power of Duncan had been weakened
by repeated defeats at the hands of the Northmen under Thorfinn. In 1057
Macbeth was slain in battle at Lumphanan, in Aberdeenshire, and Malcolm
Canmore, son of Duncan, after returning from England, whither he had fled
from Macbeth, succeeded to the throne. But he and his descendants for
long were opposed by the House of Murray, descendants of Lulach, who
himself had died in 1058.
The world will always believe Shakespeare's version of these events, and
suppose the gracious Duncan to have been a venerable old man, and Macbeth
an ambitious Thane, with a bloodthirsty wife, he himself being urged on
by the predictions of witches. He was, in fact, Mormaor of Murray, and
upheld the claims of his stepson Lulach, who was son of a daughter of the
wrongfully extruded House of Aodh.
