Wilsonn was probably the son of Robert Wilsonn, printer and stationer, of Birchin Lane and Lombard Street c.1752-77. The latter certainly had a son Richard by his wife Mary, in the same business, who died at Frome in 1785, having married in 1757 Isabella Longdon. In 1782 Charles Edward Wilsonn, a liveryman since 1774, was a stationer in Lombard Street; and in October 1784 he addressed two letters to Pitt offering to take on the office of receiver of the new window tax at a discount advantageous to the public and as efficiently ‘as I now do the old window tax account’. He claimed 20 years’ experience and wrote as ‘a sincere admirer of the present administration’.
Wilsonn was a silent Member, all of whose known votes were on the ministerial side. He opposed Catholic relief both in 1816 and in 1817. He did not seek re-election in 1818. He died 14 Feb. 1829, leaving his widow £5,000 cash and £1,425 p.a.
