This painting is a copy after George Romney’s portrait of Major General Thomas Dundas, now in the Lehigh University Art Museum, Bethlehem, PA (op. cit., p. 195, no. 389). The Lehigh portrait was painted as a pendant to the portrait of Dundas’s wife in 1785.

In his 2015 catalogue raisonné, Alex Kidson publishes this painting alongside another copy, now untraced. He suggests that the present portrait may have been made when the prime version was with Knoedler, circa 1917. Kidson further speculates that the lost copy may have been the version painted for the sitter's daughter, which was later owned by Mrs. Buchanan Baillie Hamilton of Cambusmore, Callander and the Marquis of Tweeddale.
