Unfortunately, pictures of the younger Marianne Thornton (1797-1887) – such an important family chronicler and commentator on Wilberforce and the Clapham Sect – are not easy to find. Two at least, however, are known. The first of these is a pencil and watercolour bust portrait (29 x 23 cm) dating from around 1830 by George Richmond (1809-1896). This was presented in 1947 by E. M. Forster (Marianne was his  paternal great aunt) through The Art Fund to Nottingham Castle Museum and Art Gallery. The second is a drawing mounted on card of Marianne as an old woman, dated 18 July, 1876, also seemingly by Richmond, which was printed in E. M. Forster’s Marianne Thornton: A Domestic Biography (London: Edward Arnold, 1956) [see: The Papers of Edward Morgan Forster].
