CAMPBELL, Hugh Hume, third earl of Marchmont (1708–1794), politician. Autograph letter signed 'Marchmont' to an unnamed correspondent, 1 side 4to, London 24 Decr 1777, explaining that a severe illness has kept him in London all summer, "I have heard nothing from Mr. Cockburn concerning your pedigree .............. Sir Geo. Home is a Lieutenant in a man of war in America. Others may entertain jealousies, but Mr. Cockburn ought to inform you how things stand. I believe whatever pedigree may be made nothing lucrative can follow after so long a time in neglect". Light browning to areas of text, and the reverse with old mounting marks.
Marchmont was one of the leading agricultural improvers of his time, who devoted considerable energies in developing his Berwickshire estates. He was widely read, an expert on horsemanship, and was an intimate of Alexander Pope and Sarah, duchess of Marlborough (ODNB).
