Smythe, not to be confused with Richard Smythe of Ballynetra, Co. Waterford, who was knighted in 1624 and married into the Boyle family,
Smythe became a member of Prince Charles’ Council in April 1617, and seven months later he was appointed surveyor-general to the prince. Despite these new responsibilities, Smythe remained receiver for the duchy of Cornwall, and it was probably in this capacity that in 1620 he helped raise money on behalf of Prince Charles’ sister, Elizabeth of Bohemia.
Smythe presumably used the Duchy interest to give his son Sir John II parliamentary experience by sitting for the Cornish borough of Mitchell in the next two parliaments. ‘Weak of body’, he made out his will on 12 Oct. 1627, in which he left £3,000 to his unmarried daughter, Margaret, who was a dwarf, and £100 to the London parish of St. Stephen, Coleman Street to provide a stock and buy coal for the poor. His bequests to Ashford and four other Kentish parishes totalled £57. He appointed Fanshawe and his brother William* and Thomas Brett* executors and his ‘honourable and worthy good friend’ Sir James Fullerton* overseer.
