 His son Sir William Pynsent, 2nd Baronet died without an heir in 1765 and left his estates in Somerset and Wiltshire to William Pitt the Elder, in gratitude for Pitt's opposition to a new tax of ten shillings on each hogshead of cider.Pitt kept the Somerset estates at Burton Pynsent but sold his new property at Urchfont to the third Duke of Queensberry, and the house was then occupied by tenants until it was bought by Simon Watson Taylor in 1843.In 1928, his heirs sold it to Hamilton Rivers Pollock (1884-1941), a barrister who lived there until his death.
