John Hampden, ‘a very sensible and observing man [who] would have made a figure in the world if his unfortunate brother Richard had not ruined the estate’, succeeded in 1728 to an inheritance which was entirely in the hands of government appointed trustees. However, by the sale of outlying properties, arrangements were made for him to retain Great Hampden and Wendover,
he was attacked by Hampden, who had every attribute of a buffoon but cowardice and none of the qualifications of his renowned ancestor but courage. He drew a burlesque picture of Pitt and Lyttleton under the titles of Oratory and Solemnity, and painted in the most comic colours what mischief rhetoric had brought upon the nation and what emoluments to Pitt. Pitt flamed into a rage and nodded menaces of highest import to Hampden, who retorted them, undaunted, with a droll voice that was naturally hoarse and inarticulate.
Walpole also wrote that Hampden ‘hates the cousinhood [Pitt, Lyttelton, and the Grenvilles] and thinks his name should entitle him to Pitt’s office’. In January 1752 he opposed Lord Harley’s motion against subsidy treaties in time of peace ‘but, with a sneer, said that he approved bribing electors, as he saw by other instances how it had contributed to quash opposition’. A year later he spoke in favour of Lord Hardwicke’s marriage bill.
