Gwillym was returned for Newton on his father-in-law’s interest. He suffered from bad health and seldom attended the House: his one recorded vote, 22 Feb. 1775, was for Wilkes’s Middlesex resolution, and he is not known ever to have spoken. In 1780 Robinson classed him as ‘contra’. He did not stand at the general election.
He died in France 9 July 1783.
