In November 1756 George, 3rd Earl of Orford, with whom Charles Boone had been at Eton, tried to have him returned for Callington, but had to give way to the candidate of his mother, the Dowager Lady Orford. In February 1757, and at all his subsequent elections for Castle Rising and Ashburton, Boone was returned by Orford, to whom, according to Horace Walpole, he proved ‘the single friend’ that ‘showed gratitude to him when he was no longer capable of serving anyone [i.e. when he was insane]’.
In 1761 Boone was sent Newcastle’s parliamentary whip direct. In November 1762 Henry Fox attempted to use him as an intermediary with Lord Orford.
His first recorded vote in the Parliament of 1768 was with the Administration over Brass Crosby, 27 Mar. 1771. In both Robinson’s surveys on the royal marriage bill, March 1772, he was listed as ‘pro, present’; he voted with the Administration on the Middlesex election, 26 Apr. 1773; appears in the King’s list of dissenting friends on the Grenville Election Act, 25 Feb. 1774; was classed by Robinson as ‘pro’ in September 1774; and henceforward regularly supported Administration till the fall of North. In a survey drawn up for Shelburne in August 1782 Robinson noted about Boone: ‘Is a very independent man. Was pretty closely attached to the old Administration and in long habits of friendship with Mr. Rigby and his friends; may be hopeful.’
Boone died 3 Mar. 1819, aged 89.
