In 1776 Mansfield, a successful lawyer, was offered a seat at Morpeth by Lord Carlisle, but apparently confident that he would soon obtain legal office incompatible with a seat, he refused.
Mansfield was described by Wraxall as a man ‘of acknowledged talents, parliamentary no less than professional’, who ‘manifested great energies of mind and character’.
Mansfield died 23 Nov. 1821.
