Rose’s father, a Scots episcopalian minister, was imprisoned after the ’45, and George at the age of four was ‘adopted by his mother’s brother, at the time living in Hampstead, and educated by him’. He entered the navy ‘at a very early age’, serving in the West Indies; finding promotion barred, he left, but retained all his life an interest in the sea and in naval matters. ‘Through private friendship [he] was appointed a clerk in the record office’, and his work on the journals and rolls of Parliament brought him into touch with Lord Marchmont, chairman of the Lords committee dealing with their records, who assisted him in his career.
Rose was involved in the plans for turning out the Coalition, and Charles Jenkinson on 5 Dec. 1783 advised Robinson that Thurlow should be approached ‘through Mr. Rose’.
Daniel Pulteney thought that, ‘except Rose and Stephens, there is hardly one man of any service either in the Treasury or the Admiralty’; but he later criticized Rose: ‘Such stuff is brought into the House by Rose and Steele, and frequently passed, as occasion great triumph to the Opposition.’ Pitt ought to beg, borrow or buy some abler assistance.
Despite his close association with Pitt, he differed from him on two points—parliamentary reform and the slave trade. He declined ‘after repeated solicitations to vote with him in his motion for parliamentary reform’. ‘In so nice a matter I must be governed by my own feelings.’ He feared that ‘if a breach should once be made in the representation’, nothing could prevent ‘in a short time, its being widened to a ruinous extent’. Because of this disagreement he offered to retire, but Pitt would not allow it.
In the summer of 1785 he tried unsuccessfully to help Orde with the Irish commercial resolutions. He wrote to Orde on 25 July: ‘Anxious as I was to avoid the resolutions going, I could not urge Mr. Pitt further than to endeavour to convince the Cabinet, which he did with all possible earnestness—failing in that, it was too much to press him to act against their united opinions.’
In June 1788 Rose succeeded to the clerkship of the Parliaments, of which he had been awarded the reversion in 1782 for his services to the Lords. This necessitated his re-election, but relations with Percy, since 1786 Duke of Northumberland, had been uneasy for several months, and now the Duke, complaining of ‘neglect by the minister’ (although he had received the Garter two months previously), demanded appointments for certain protégés before he would re-elect Rose; who replied that
no circumstances, nor any consideration whatever, could now induce me to owe a fresh obligation to your Grace ... I had great doubts whether you would be disposed to re-elect me; or ... whether ... I should think it possible, consistently with my feelings, to accept of such re-election; those doubts are removed by your Grace’s letter of last night.
Add. 42774 A, ff. 51-55.
Consequently Rose had to find another seat; and Harry Burrard made way for him at Lymington. By 1790 he had established at Christchurch, near his estate of Cuffnells, an interest of his own, having ‘directed the Treasury artillery’ against its electors.
Rose by this time was receiving a considerable income from his several offices and sinecures, principally £3,000 as secretary of the Treasury and, in 1789-90, rather more than £1,100 as clerk of the Parliaments. Shortly before the dissolution in 1790 Alderman Sawbridge alleged in the House that Rose’s broker had been involved in malpractices, a charge which he was forced publicly to withdraw at the threat of a duel.
He died 13 Jan. 1818.
