Buynbury came of an ancient Cheshire family with estates near Chester, for which he sat as a High Church Tory uninterruptedly from William III’s last Parliament to the end of the reign of George I. ‘Gay, good-humoured, and lively’, he was an intimate friend of George Farquhar, who drew from him the character of Sir Harry Wildair.
Losing his seat in 1727, he died on 12 Feb. 1733.
