A Perthshire laird, hailing from a cadet branch of the staunchly Royalist earls of Kinnoull, Hay came of age politically under the protection of the Murrays of Atholl, entering the Scottish administration in 1696 with John Murray, earl of Tullibardine [S], later duke of Atholl [S]. But although he remained close to Tullibardine he soon found alternative patrons, first Tullibardine’s great rival James Douglas, 2nd duke of Queensberry [S], and much later the English Tory politician Robert Harley, later earl of Oxford, to whom he became connected by marriage. Hay retained residual ‘cavalier’ sympathies throughout his political life but the traces of these loyalties became fainter the more he engaged with government. The turning point in his career was the return from Jacobite exile of his distant cousin, William Hay, 6th earl of Kinnoull [S], in about 1699.
When Tullibardine returned to office in 1702 Dupplin may have re-established their former close relationship, for he certainly received an expensive present from Atholl (as Tullibardine had since become) in May 1704 and he did not suffer as a consequence of the ministerial experiment of 1704, which saw Queensberry replaced as commissioner, and responsibility for managing the Scottish parliament entrusted to the ‘New Party’ (or ‘Squadrone Volante’).
In the preparations for the 1708 elections Dupplin was again used by Mar and Queensberry as an intermediary with Atholl, with mixed results.
Dupplin had already established a correspondence with English political figures such as the lord treasurer, Sidney Godolphin, earl of Godolphin, and his personal affairs (including, presumably, ongoing solicitations for the payment of his pension) ‘obliged him to be in London almost every winter’.
After the fall of Godolphin Kinnoull openly identified with Harley’s new ministry, on whose behalf he worked, with Mar, in preparations for the 1710 elections. His friendship with Atholl was again important, in brokering a deal between Atholl, Hamilton, and Queensberry’s interest.
Kinnoull’s career in the British Parliament was distinctly lacklustre, constrained by poor health and his reluctance to leave Scotland. After the peerage election, Kinnoull wrote to Harley of his intention to leave Edinburgh on 13 Nov., so as to ‘be with you against the Parliament sit down’.
Dupplin wrote to Harley (now earl of Oxford and lord treasurer) on his father’s behalf on 10 July 1711, explaining that Kinnoull was disappointed that he had not been accorded a central place in the management of Scottish affairs. He had hoped to be made lord clerk register, and to be able to influence the direction of Scottish policy:
he would not at all meddle in Scotch affairs by halves, if a thorough measure for the interest of the crown (which by his notion is the only way Scotland can reap advantage by the Union) were not gone into, and pursued without respect to private recommendations, without fear of disobliging or desire of obliging anybody or any party.
However,
at some certain times I have found him in quite another humour, that he desired nothing in the world so much as to go home and plant his trees and live easily in the country. What had he to do to be chosen one of the 16 to come to London and make himself a show with his gout? And a world of such splenetic fancies, which I took not at all to be what he really desired, but only to proceed from the delay he found was like to be in doing anything in Scotch business.
At the same time, if Oxford called his bluff,
He’ll be very dissatisfied, and will never make good what he so often declares, that no man desires more to live a private life at home at his ploughs than he does. He’ll be worse than he was winter was a twelvemonth, when I assure you there was no bearing of him, not by his children or servants, even though he was in this pleasant country way of living he talks of.HMC Portland, v. 33-34.
No office was forthcoming, nor did Kinnoull’s renewed petition to the treasury about February 1711 for arrears of his annuity (which he estimated at over £17,000) elicit a concrete response, but he seems to have been mollified by encouraging letters from Oxford, and as the next session approached he was making professions of loyalty and offering Oxford advice on the management of Scotland.
As late as 27 Nov. 1711 Mar was vexed about the non-appearance of the Scottish peers in London for the session prorogued on that day to 7 December. Mar wrote to his brother Hon. James Erskine‡ Lord Grange SCJ, to hurry the peers along: he had himself written to Kinnoull ‘in case he be not come off, but if he be, send it to him by the post to be left at some stage so that he may get it and send you with the draught of a proxy’.
In June 1712 it looked as if Kinnoull’s ambition to be lord clerk register was about to be fulfilled, but by the beginning of July William Johnston, marquess of Annandale [S], had emerged as the favourite to replace David Boyle, earl of Glasgow [S], who, in the event, retained the post.
Once the session was over Kinnoull wrote to Oxford on 2 July 1713 to recommend not only that ‘the malt tax be set to rights’, but also that the Campbell brothers, John, 2nd duke of Argyll [S], and Archibald, earl of Ilay [S], prime movers in the attack on the Union, be ‘turn[ed] out of all they can be turned out of’.
On 30 Jan. 1714 Findlater in Edinburgh informed Oxford that both he and Kinnoull would be ‘detained all the next week’ because of the marriage scheduled for 4 Feb. between Kinnoull’s daughter and his heir, James Ogilvy†, the future 5th earl of Findlater.
Kinnoull was not elected to Parliament in 1715. In late August of that year he was arrested on rumours of Jacobite military preparations in Scotland and confined to Edinburgh castle. Agitation by his friends on the grounds of his poor health and his loyalty to the Hanoverian regime eventually resulted in his release in March of the following year.
Kinnoull died (perhaps inevitably of gout) at Dupplin House on 5 Jan. 1719.
