Griffith, the seventh of the family seated at Garn, was a country gentleman active in the corporation of Denbigh. In 1806 he encouraged the candidature of Robert Biddulph against his brother-in-law Frederick West, and in 1812 led the Whig faction supporting Biddulph in the contested election.
Griffith retired in 1826 and died 20 June 1834. He was a keen botanist, agricultural improver and sportsman, as most of his surviving correspondence with his family attests.
