 In both of these charters, the grants are to native Scots and Gille Coluim appears alongside other native Scots, such as (in both cases) Gille Críst mac ingine Samuel ("Gillecrist mac inien Samüel") and Gille Míchéil mac Donnchada ("Gillemichel mac Dunecan").Gille Coluim in both cases appears with the title "Marescal", meaning that he was the king's military commander.It appears to be in this role that Gille Coluim was given control of the castle at Auldearn ("Heryn") in Moray during a rebellion by the Meic Uilleim, a royal kindred who were claiming the throne of Scotland.
