Returned for Renfrewshire in 1722 on the Dundonald interest, Cochrane seems to have been a follower of the Duke of Argyll, to whom, as governor of Minorca 1712-16, he probably owed his Minorca appointment. This appointment gave rise to a lawsuit with his predecessor in 1726, when Cochrane’s counsel was Duncan Forbes, Argyll’s henchman, Robert Dundas, a member of the anti-Argyll faction, the Squadrone, appearing for his opponent.1 He did not stand again. He was in Edinburgh during the Forty-five, afterwards giving evidence against the Provost, Archibald Stewart, at his trial for surrendering to the rebels.2 Succeeding to the Dundonald earldom in 1758, he died 27 June 1778, leaving his son ‘a mass of debts and pressing creditors’.3
