Spencer-Stanhope is the family name of British landed gentry who for 200 years held Cannon Hall, a country house in South Yorkshire that since the 1950s has been a museum.
Throughout the 19th and early 20th century, several family members (by birth and marriage) were active in the art world.
They were related through John Spencer Stanhope (1787–1873), a classical antiquarian, writer, and explorer, and his wife, Lady Elizabeth, daughter of Thomas Coke of Norfolk, 1st Earl of Leicester.
John Spencer Stanhope was the son of industrialist Walter Spencer-Stanhope (1749–1822).
The couple died in 1873 within a few days of each other; she on 31 October, he on 7 November.
