After a miniature by Samuel Shelley dating from the early 1780s (43897; Royal Collection) and a pair to Lee's enamel of Henry Frederick, Duke of Cumberland (421840). Anne, Duchess of Cumberland, daughter of Simon Luttrell, Baron Irnham, and widow of Christopher Horton, married, in 1771, Henry Frederick, Duke of Cumberland. She and her sister, Lady Elizabeth Luttrell, immortalised by Thomas Gainsborough at the height of their beauty and success in the mid-1780s (400675; Royal Collection), outlived the Duke of Cumberland and died in poverty abroad.

Joseph Lee (1780-1859) was self-taught as an an enamellist at a late age, but made a successful career as an enamel painter, exhibiting intermittently at the RA and the SBA between 1809 and 1853 from addresses in London. He styled himself as 'enamel painter' to Princess Charlotte of Wales and later worked as 'enamel painter' to Augustus, Duke of Sussex. It may have been the gift of a small enamel of the Duke of Sussex to Queen Victoria that first made her familiar with Lee's work. She employed his services for producing enamel copies based on oil paintings between 1844 and 1850. He retired from miniature painting in his final years and died, aged seventy-nine, in Gravesend, Kent, on 26 December 1859.
