Wenman’s father sat for Oxford 1749-54 and was a Tory candidate at the great Oxfordshire election of 1754; and Wenman was returned for the county at five general elections without a contest. The English Chronicle wrote about him in 1781: ‘Of a Tory family, but of an honest, independent, upright conduct in Parliament, and inclined to Opposition.’ He was closely connected in politics with his brother-in-law, Lord Abingdon, and voted consistently against the Grafton and North Administrations. Abingdon wrote to Shelburne, 13 Feb. 1783:
He died 26 Mar. 1800.
