The painting depicts Grosvenor Bedford (1708-1771) resting his right arm on a chair, his wife, Jane Bedford nee Grosvenor (1712-1759) who was his first cousin, is seated and on the right is his eldest son and heir, Charles, holding a riding whip. Bell dates the Exeter painting c.1747-8, a date that is consistent with the likely age of Charles.
Grosvenor Bedford (1708-1771) held positions in government and was favoured by the powerful Walpole dynasty. A friend and patron of the artist, his influence would have opened doors to further commissions.
