Dated by David Mannings (op. cit.) to circa 1768, this portrait was traditionally thought to show John Parker, 1st Lord Boringdon (1735-1788), no doubt due to an old inscription on a similar portrait of the same sitter at Saltram House, Devon (Mannings, op. cit., p. 367, no. 1399). Mannings believes the sitter for both portraits to be Boringdon’s younger brother, Montague Edmund Parker (1737-1813), who lived at Whiteway House, Devon.
