He moved with Maria to Cheltenham in 1841, most likely because living at Bramall had become expensive or because of health concerns. Salusbury died there four years later and was buried in Leckhampton.Over the next decade the house was likely to have been let, as Maria Davenport preferred to live elsewhere.
