Folk Figure. Born Raibeart Ruadh MacGriogair in Glengyle, at the head of Loch Katrine, the third son of Donald of Glengyle, a clan chieftain, and Margaret Campbell. He married Mary Helen MacGregor of Comar in Glenarklet in 1693. Records name four sons; James, Ranald, Coll; and Robin Oig, or Young Rob. Because of the Proscription of 1603, which banned the name of MacGregor, he often used his mother's maiden name, Campbell, instead of his clan name. Although he was a clan war chief he was never clan chief himself, but Laird of Inversnaid, a position held at the sufferance of the Duke of Montrose, his patron. He followed the respectable career of cattle dealer. Between 1691 and 1712, he led a prosperous life, and Montrose granted him the rights to the properties of Inversnaid and Glengyle. After 1712, a depression and famine hit the highlands and he lost his house, lands, and the patronage of Montrose. He exchanged the life of cattle dealer for that of bandit, and Montrose for Argyll. He became the Duke of Argyll's enforcer, and established a very early form of protection racket – payment would ensure a man's cattle remained on his own lands. During the Jacobite Uprising of 1715, he acted as a Jacobite guide for the march from Perth to Dunblane, but after the rising collapsed, he wrote that the rebellion had been forced upon him, and that he supplied Argyll - his patron who had remained on the opposing side - with intelligence as to the strength and composition of the Jacobite army. Afterward, he continued his career as a brigand, and his exploits included the kidnap of Montrose's factor, John Graham of Killearn. During his career, he was captured more than once, but managed to escape each time. In 1726, he received a full pardon for all his criminal activities, and retired to his home, a legend in his own time. He died at home in Inverlochlarig Beg, Balquhidder, at the age of 63. He was buried In Balquhidder Kirkyard. The ornamental bronze rail around his grave gives his age incorrectly as 70. His epitaph, 'MacGregor Despite Them' is a reference to the proscription of his clan name. Author Sir Walter Scott penned the fictionalized account of his life in the novel, "Rob Roy" published in 1818.
