Offices Held

Gent. usher of the black rod [I] 1763-5.


Edmonstone came of an ancient and strongly Presbyterian family which, during the plantation of Ulster, purchased the estate of Broad Island, co. Antrim, and thereafter divided their interests between Ireland and Scotland.1 His father acquired additional property in Dunbartonshire, but resided mostly in Ireland.

Lord Chesterfield wrote to Solomon Dayrolles, 21 Sept. 1753:

Your friend Mademoiselle Harenc is to be married ... to one Mr. Edmonstone, a Scotch gentleman, whose father has an estate in Scotland and Ireland of about £1500 a year. He is ... under the protection of the Duke of Argyll, by whom he expects to be brought into Parliament. He is strong, well set, and promises to make a considerable husband. Harenc gives £10,000 down with his daughter.

Edmonstone’s hopes of a seat at the 1754 election were disappointed. He seems to have entered business with his father-in-law,2 and was not mentioned as a candidate in 1761 until, by the death of Argyll during the general election, Edmonstone’s uncle succeeded as 4th Duke, and Dunbartonshire thereby became vacant. Bute hoped for ‘time ... to look about us’,3 but the Campbells’ hands were forced by the appearance of Robert Haldane as a candidate. The new Duke wrote to Bute, 6 May 1761:4

I am in hopes of hearing soon from you on the subject of the plan I proposed towards bringing my nephew Mr. Edmonstone into Parliament for the county of Dumbarton, meantime—as Mr. Haldane has been in the county with a view to offering his service I thought no time was to be lost by taking some measures to secure it for the interest of our families ... I have accordingly recommended my nephew which I am hopeful will be agreeable to your Lordship. He is a man of considerable property both in Dumbarton and Stirlingshire and I have good reason to believe will follow my advice and consequently your Lordship’s.

Haldane having withdrawn, Edmonstone was returned unopposed. Bute now took the Duntreath Edmonstones into favour and obtained for Archibald’s brother Campbell the lieutenant-governorship of Dumbarton castle.

Edmonstone loyally supported the Bute and Grenville Administrations, and in the summer of 1763, having been appointed gentleman usher of the black rod, accompanied Northumberland, the new lord lieutenant, to Ireland. In anticipation of the Wilkes debates, Grenville asked Northumberland, 22 Sept. 1763,5 to send Edmonstone, ‘whom I have reason to believe as well inclined as possible’, over to England. He returned and voted with Administration in the division of 15 Nov. Listed as ‘doubtful’ by Rockingham in the summer of 1765, he lost his place, and went into opposition. Albemarle wrote to Rockingham, 16 Feb. 1766:6 ‘Mr. Edmonstone will vote against you and go with the young Campbells, if the Duke of Argyll, who chooses him, does not lay his commands upon him.’ Edmonstone voted with his cousins Lord Lorne and Lord Frederick Campbell against the repeal of the Stamp Act on 22 Feb. He voted with the Chatham Administration on the land tax, 27 Feb. 1767, and on nullum tempus, 17 Feb. 1768.

Edmonstone was a conscientious Member, frequently appointed to committees, particularly on road bills; piloted the Glasgow roads bill through the House in 1766; and from 1762 was actively concerned in the transactions for paving Westminster streets.

In the new Parliament he continued to support Administration. He intervened in the debate of 15 Apr. 1769 on the Middlesex election;7 and in March 1771 on the printers’ case.8 In September 1771 the Argyll interest obtained from North the place of receiver general of Scottish customs, worth £1500 p.a. A London newsletter records:9 ‘It is to be divided between Mr. Edmonstone of Duntreath and Colonel Campbell of Finab who is to go out of Parliament.’ At the general election of 1774 he was returned after a contest with George Keith Elphinstone, who brought a petition, subsequent
