Although a younger son, Primrose was evidently a favourite of his distinguished father and was left a substantial part of Lord Carrington’s fortune, including the estate at Dalmeny. He also inherited some of his father’s political skills, if not his intellectual brilliance, and was able to make a career at court and in government. After a period of foreign travel which culminated in active service in the Austrian Imperial army against the Turks in Hungary, he came home in 1687. The following year he found himself summoned before the Scottish Privy Council for opposing the religious policies of James II; proceedings were halted by the intervention of James Fitzjames, duke of Berwick, and it is said that to save himself Primrose ‘declared Popish’.
After the 1688 Revolution Primrose received a position in the royal household (at a salary of £600 p.a.) and from 1696 served as a commissioner for Edinburghshire (Midlothian) in the Scottish Parliament.
He remained loyal to Queensberry throughout the shifts in Scottish politics after the accession of Anne. In 1703 he was reappointed to the Scottish Privy Council, promoted in the peerage, and granted the post of chamberlain of Fife and Strathearn (at a combined salary and pension worth £300 p.a. in total), as part of a package of preferments designed to buttress Queensberry’s position.
For Rosebery this was not enough. He was owed nearly £3,000 in arrears on his pension for the chamberlainry of Fife and Strathearn; a further £1,500 from his salary as a union commissioner in 1702–3; and in all probability another substantial sum from unpaid salary as a gentleman of the bedchamber to Prince George (the arrears of which amounted to £750 at the prince’s death in 1708).
reasonably now expect some other post in the government than that only of being a commissioner, for your lordship knows I ever firmly served her majesty, and her interest, in all the sessions of Parliament I have been in and have been obliged to be at some expense in attending her service, but whatever her majesty may be pleased to do in this it shall never in the least alter the zeal I have always had for her service.NAS, GD124/15/581/1-2.
In the 1707 analysis of Patrick Hume, earl of Marchmont [S] he was described as ‘sicut [i.e. just as] Queensberry’. Although Parliament met on 23 Oct. 1707, Rosebery was the last Scottish representative peer to take his seat. He swore the oaths on 1 Dec., beginning a parliamentary career that covered seven sessions. He attended all but one of those sessions for more than half of all sittings and four sessions for more than 60 per cent. The timing of his initial attendance coincided with heated debate in the Commons on how to strengthen the Union. Two bills were sent up to the Lords during January and February 1708: the first, to abolish the Scottish Privy Council and introduce into Scotland the English system of justices of the peace; the second to settle the militia in Scotland.
Rosebery had attended the session for the last time on 12 Mar. 1708, eight days after the House had received papers relating to an invasion attempt from France on behalf of the Pretender. He was in Edinburgh by the end of the month but was not present at a shire meeting on 5 Apr. when an address was agreed ‘asserting her Majesty’s right against the prince of Wales and all pretenders whatsoever’. His absence was hard to explain: Sir John Clerk, bt., of Penicuik, an austere Presbyterian and ‘Revolutioner’, accused those Midlothian lairds who had failed to attend of being ‘against the union either within or without doors’.
In the opinion of the Scottish customs commissioner Sir Alexander Rigby‡, writing shortly after the election to James Ogilvy, earl of Seafield [S] (later 4th earl of Findlater [S]), Rosebery ‘hath too long neglected himself and therefore I doubt he’ll find it hard to shake off some habits; otherwise he is well worth caressing as most lords of this country, being a sensible, reserved, well bred and indefatigable gentleman’.
Before the next session Rosebery finally obtained some reward for his patient pursuit of preferment, when his grant of the chamberlainry of Fife was converted to a patent for the life of the queen, with a salary of £300. It would seem that he was no longer chamberlain of Strathearn under the new dispensation, though he did continue to collect the rents and keep back the proportion which had previously been allowed him as a pension.
Rosebery was re-elected a representative peer in November 1710, having been included on the list agreed in advance between Mar, James Hamilton, 4th duke of Hamilton [S], and John Campbell, 2nd duke of Argyll [S].
By the time he came down to London in November 1710, Rosebery was back on good terms with Mar, sharing his coach on the journey: Mar found his company ‘diverting’.
Despite the renewal of his appointment as chamberlain of Fife, Rosebery still harboured insecurities about his position, principally because of a prior claim to the office being advanced by Sir John Malcolm‡, bt. the recently elected Tory member for Kinross-shire. Rosebery proposed to the lord treasurer (Robert Harley, earl of Oxford) that his remuneration be altered from a combination of salary and pension to salary only, in order to facilitate a compromise agreement with Malcolm, but the barons of the Scottish exchequer would not approve the arrangement.
Rosebery sought to capitalize on his value to the ministry in the summer of 1712 by urging again a resolution of his insecurities over the Fife chamberlainry and the payment of the arrears due to him. He renewed the request that his existing pension be converted into a salary, and secured for a period of 32 years, and also for the payment of £1,000 arrears.
Naturally, the crisis over the extension of the malt tax to Scotland put him into a difficult position. Just before the Scots peers were to meet on 27 May 1713 to discuss their response to the malt bill, Rosebery dined at his lodgings with Henry St John, Viscount Bolingbroke, and Alexander Montgomerie, 9th earl of Eglinton [S].
Before the 1713 election Oxford was reminded yet again of Rosebery’s ongoing ‘pretensions’: the monetary arrangements of the chamberlainry were still not adjusted to his satisfaction, and arrears of salary from his household office were still outstanding.
Rosebery did not sit in the Lords again after 1714. He steered well clear of Jacobite intrigues, but remained a Tory in his political leanings. He signed the petition against the peerage bill in 1719 and supported Tory candidates in the 1722 peerage election.
