Whitmore was heir to ‘extensive mercantile establishments’.
I shall have great pleasure in giving my support to Mr John Whitmore, a Bank director, and one of the commissioners for the support of private credit under the Act of 1793. He is first cousin to the deceased, and I hope will be prevailed upon to be a candidate. Give me leave to say, that he will be a valuable acquisition to the House of Commons.
Browne added that he was sure Whitmore would not be ‘in the same political system’ as his late cousin, a Foxite Whig.
Whitmore was a silent supporter of Pitt’s administration. He was one of the City men who met on 27 Nov. 1795 to pledge their support to government and again on 7 June 1797 to express their abhorrence of the naval mutiny.
