Portrait of a Gentleman, probably George, Viscount Lewisham (d. 1732), three-quarter-length, in a blue coat and waistcoat, in a landscape

The presumed sitter, the eldest son of William, 1st Earl of Dartmouth, married Elizabeth, daughter and heiress of Sir Authur Kaye, Bt. Elizabeth married secondly in 1736, as his second wife, Francis, 7th Baron North, created 1st Earl of Guilford in 1752.

The chalk inscription of 'Col. North' on the reverse presumably refers to Col. John Sidney Doyle, who married Susan, Baronness North (great-granddaughter of 1st Earl of Guilford) in 1835, and assumed the surname of North in 1838.
