Two major interests contended for control of the county: the Homes, earls of Home, and the Humes, earls of Marchmont, branches of a family which had separated in the fifteenth century, and were at bitter odds with each other. Hugh, 3rd Earl of Marchmont, was an able, rich, and arrogant politician, violently jealous of Argyll’s power as ‘viceroy’ of Scotland. William, 8th Earl of Home, whose father had been imprisoned on suspicion of Jacobitism, was an impoverished army officer who had the consistent support and affection of Argyll.
From 1734 Marchmont’s twin brother Alexander Hume Campbell had represented the county, and in 1754 he was returned unopposed. Newcastle, anxious to secure his support against Pitt, appointed him lord clerk register in 1755, and acceded to almost every request from Marchmont on Berwickshire patronage.
If they could be assured there would not be an opposition ... they might not be so anxious about the lieutenancy, for their chief apprehension is of a defeat (and what they will think a disgrace) in the county election, and to guard against that they push the point of dispossessing Lord Home of the lieutenancy.
The attempt failed, but throughout 1758 and 1759 Marchmont and Home competed for patronage; and Marchmont attributed every disappointment to the ‘unrelenting resentment’ of Argyll.
As the general election of 1761 approached, the Home party invited Sir John Hall of Dunglass to stand; and when Hume Campbell died suddenly on 19 July 1760, Hall was forced to make an immediate decision as to whether or not he would become a candidate. His friend Lord Elibank wrote to him on 28 July:
This is the time to make a struggle; in submitting now you seem to me to surrender yourselves forever. If Lord Marchmont shall fix on a popular man, he will strengthen his own interest and get into the undoubted possession of disposing of the shire forever at pleasure. ... Such a man will be more dangerous to your independency than Hume Campbell. On the other hand if you stand, as you are known to be of no party and have connexions with many who have been attached to Lord Marchmont, he cannot with any face oppose you.
While Hall hesitated, other candidates were mentioned, among them James Pringle, son of Marchmont’s friend Sir Robert Pringle, James Kerr of Moriston, Sir Alexander Don of Newton, and Alexander Renton of Lammerton.
Home and Argyll both died in April 1761, and with their deaths some of the animosity between the two sides in Berwickshire disappeared. Pringle was a popular figure with both, and the Marchmont hold on the county was strengthened. In 1779 Pringle vacated his seat in favour of Marchmont’s son-in-law, Sir John Paterson, who was returned unopposed. But the choice of Paterson, a gambler of evil reputation, notorious for his sharp practices, was unpopular. At the general election of 1780 the Berwickshire gentry, with the support of the Home interest, prepared to oppose Paterson. Alexander Renton was again a candidate, but a more formidable one was Hugh Scott, grandson of Marchmont, who refused him support. Marchmont’s anger was intensified when there came into his possession an indiscreet letter, written by Scott’s father, ridiculing Marchmont’s pretensions; and a violent family quarrel ensued.
At the general election of 1784 Scott did not stand, and Patrick Home of Wedderburn was returned unopposed. In Marchmont’s absence his interest disintegrated, and by 1789 he had ‘given over all outward appearance at least of interfering in any public concern’.
Number of voters: about 50 in 1760, 85 in 1780, 153 in 1788
