Murray’s father took part in the 1715 and 1719 rebellions, escaped abroad, returned home on a pardon, and settled on his wife’s estates. Young Murray was brought up by his Hanoverian uncle, Duke James, who in 1745 obtained for him a commission in Loudoun’s new regiment.
My father has declared for the Pretender, which of all things I was most afraid of, but as your Grace, who has so long been at the charge of my education, is for King George ... I shall lay down my life ... in his service. For although my father be not so much in the wrong ... as he has been for that party always ... yet it would be the greatest baseness in me ... not to be for King George as I have a commission from him and have always been educated as his subject ... I should be very much obliged to you if you would let me leave school and come down to Scotland, for I don’t doubt I could handle a broadsword or a musket well enough ... for though I love my father ... yet it is impossible for me to think that he has acted right.
Murray, however, was not allowed to serve, and in 1746 was deprived of his commission.
On returning home from Göttingen, John was married to his cousin, engaged in the management of Atholl’s estates, and was groomed for leadership in county politics. On 1 Apr. 1760 he presided at a meeting to petition Parliament for a Scottish militia; and shortly afterwards announced his candidature for Perthshire against his half-uncle Lord John Murray, and with Argyll’s backing was returned.
Freed by his father’s death, in October 1760, from suspicion of disloyalty, he entered Parliament as a firm supporter of Administration, attached himself to Bute, voted for the peace preliminaries, and supported Grenville’s Administration. On Atholl’s death, 8 Jan. 1764, Murray, although legal opinion unanimously supported his right to succeed to the dukedom, decided to petition the Lords for confirmation; and on 7 Feb. was confirmed in his right to the titles. In his later years Atholl became something of a recluse and lost much of his popularity. In 1774 he was stricken with apoplexy, accidentally drank a cup of hartshorn, and in delirium drowned himself in the Tay, 5 Nov. 1774.
