Clan MacGregor

The Clan Gregor held lands in Glen Orchy, Glenlochy and Glenstrae. According to Iain Moncreiffe the MacGregors were descended from an ancient Celtic royal family, through the Abbots of Glendochart. This is alluded to in the clan's motto: "Royal is my race". There is a tradition that Gregor was the son of Kenneth MacAlpin, which is supported by the Scottish historian, William Forbes Skene, but there is no evidence to support this tradition. It is possible that he might have been Griogair, son of Dungal, who was allegedly co-ruler of Alba.
