John Bance was a merchant, trading to Hamburg, who served his apprenticeship with the firm of Jan Berewent of Amsterdam.
At the general election of 1741 Bance lost his seat at Westbury but was returned for Wallingford, which his brother-in-law, James Lamb, had contested unsuccessfully in 1740. He was included in the opposition list for a committee on the public accounts;
In 1747 Bance rejected an offer by Pelham of a compromise at Westbury and Wallingford, claiming that ‘both boroughs were under his command and he would bring in whom he pleased’.
Bance died 23 Feb. 1755, leaving £1,000 to Dodington and the same amount for the relief of the widows and children of poor dissenting ministers. His will shows him to have been a man of considerable wealth.
