The family of Lord Tullibardine, at that time called Lord Murray, furnish one of those numerous instances which occur in the reign of William the Third, of an open avowal of Whig principles, joined to a secret inclination to favour the Jacobite party. The Marquis of Athole, the father of Lord Tullibardine, had been a powerful Royalist in the time of Charles the First; but had, nevertheless, promoted the Revolution, and had hastened, in 1689, to court the favour of the Prince of Orange, with whom his lady claimed kindred. Disappointed in his hopes of distinction, the Marquis returned to his former views upon the subject of legitimacy; and finally retired into private life, leaving the pursuit of fortune to his son, Lord John, afterwards Earl Tullibardine, and Marquis of Athole. The disgust of the old Marquis towards the government of William the Third, and the evident determination which his son soon manifested to ingratiate himself with that monarch, had, at the time when the death of Hugh Lord Lovat took place, completely alienated the Marquis from his son, and produced an entire separation of their interests.[127] In his zeal for the King's service, Lord Tullibardine had endeavoured to raise a regiment of infantry; and it happened, that at this time Simon Fraser, as he expresses it, "by a most extraordinary stroke of Providence, held a commission in that regiment." This commission had been procured for him by his cousin, Lord Lovat, who looked upon it as the best means of "bringing him out in the world," as he expressed himself. The mode in which Simon was induced by Lord Murray to accept of this commission, and the manner in which he was, according to his own statement, induced to support a scheme which was adverse to the interests of King James, is narrated in his own Memoirs. If we may believe his account, he opposed the formation of this regiment by every exertion in his power: he aided the Stewarts and Robinsons of Athole, devoted Jacobites, and determined opposers of Lord Murray, whose claims on them as their chieftain they refused to admit; and when Lord Murray, on being appointed one of the Secretaries of State, resolved to give up the colonelcy of the troop, he tried every means in his power to dissuade his cousin, Hugh Lord Lovat, to whom it was offered, from accepting the honour which it was inconsistent with his principles to bear. This conduct, according to the hero of the tale, was highly applauded by the old Marquis of Athole, who even engaged his young relative, Simon, to pass the winter in the city of Perth with the younger son of the Marquis, Lord Mungo Murray, in order that they might there prosecute together the study of mathematics.
