Lord John Murray, brother of James, second Duke of Atholl, who came over with him when he took possession of the Island.

The account of the Duke's entry into Man in 1736, taken from a manuscript that belonged to the Stevensons of Balladoole, names the company. The Duke was accompanied by Lord John Murray his brother, Sir Patrick Murray of Balmanno, John Murray Esquire the Principal Clerk of Sessions, Patrick Lindsay member for Edinburgh, and Major Stevenson of the fourth troop of Guards, son to John Stevenson the Speaker of the Keys. Lord John and his company reached the Island on the Saturday morning, 19 June, the day the Twenty-Four Keys waited on the Duke with their address as representatives of the people, and the Duke went on attended by them and by many others.

He was a soldier by profession, and his regiment appears among those listed in the army accounts laid before the Commons.
