For known versions of this portrait, see J. Kerslake, Early Georgian Portraits (National Portrait Gallery), 1977, p. 42: one at Holland House is believed to have been taken in 1735 (see Earl of Ilchester, Catalogue of Pictures belonging to the Earl of Ilchester at Holland House, 1904, no. 222); another is at Blair Castle (see Kerslake, op. cit., pl. 113). The composition is varied in versions at Windsor, where Prince Charles is shown with the Order of the Garter, and in a Private Collection (reversed, with Garter). Giles Hussey was in Rome 1730-7; the Young Pretender was born there in 1720 and was largely brought up by his father at the Palazzo Muti
