It is singular that, beholding his father thus cherished by Government, the Marquis of Tullibardine should have adopted the cause of the Chevalier: and not, as it appears, from a momentary caprice, but, if we take into consideration the conduct of his whole life, from a fixed and unalienable conviction. At the time of the first Rebellion, the Marquis was twenty-seven years of age; he may therefore be presumed to have been mature in judgment, and to have passed over the age of wild enthusiasm. The impulses of fanaticism had no influence in promoting the adoption of a party to which an Episcopalian as well as a Roman Catholic might probably be peculiarly disposed. Lord Tullibardine had been brought up a Presbyterian; his father was so firm and zealous in that faith, as to excite the doubts of the Tory party, to whom he latterly attached himself, of his sincerity in their cause. According to Lord Lovat, the arch-enemy of the Athole family, the Duke had not any considerable portion of that quality in his character, which Lord Lovat represents as one compound of meanness, treachery, and revenge, and attributes the hatred with which Athole persecuted the brave and unfortunate Duke of Argyle, to the circumstance of his having received a blow from that nobleman before the whole Court at Edinburgh, without having the spirit to return the insult.[44] It appears, from the same authority, that the loyalty which the Duke of Athole professed towards King William was of a very questionable description. It becomes, indeed, very difficult to ascertain what were really the Duke of Athole's political tenets. Under these conflicting and unsettled opinions the young Marquis of Tullibardine was reared. There seems little reason to doubt that his father, the Duke of Athole, continued to act a double part in the troublous days which followed the accession of George the First. It was, of course, of infinite importance to Government to secure the allegiance of so powerful a family as that of Murray, the head of whom was able to bring a body of six thousand men into the field. It nevertheless soon appeared that the young heir of the house of Athole had imbibed very different sentiments to those with which it was naturally supposed a nobleman, actually in office at that time, would suffer in his eldest son. The first act of the Marquis was to join the Earl of Mar with two thousand men, clansmen from the Highlands, and with fourteen hundred of the Duke of Athole's tenants;[45] his next, to proclaim the Chevalier King. Almost simultaneously, and whilst his tenantry were following their young leader to the field, the Duke of Athole was proclaiming King George at Perth.[46] The Duke was ordered, meantime, by the authorities, to remain at his Castle of Blair to secure the peace of the county, of which he was Lord-Lieutenant.
