As a result, the English king bestowed the Lennox earldom on Sir John Menteith, who was holding it in 1307 while the real earl was with King Robert in his wanderings in the Lennox country.
It was perhaps to ease this process, that his mother Marjorie became an informant of the English crown.
Maol Choluim assisted Edward initially by raising men from his Mormaerdom.
Maol Choluim was in fact one of the most loyal followers of Bruce, and was rewarded by both Bruce and by later pro-Bruce writers such as John Barbour and John of Fordun, who wrote much praise of him.
Maol Choluim died in 1333 fighting for the Bruce cause against the Anglo-Balliol alliance at Battle of Halidon Hill.
