 Plans for 3 Counties Asylum dated 3 May 1877 and 9 March 1878 give his address as 3 Stonegate, York.Further works at 3 Counties dated February 1880 give his address as 100 Micklegate, next to 'The Pack Horse' and he still held the property in 1886.However, since by this time Jones had in all probability retired to Malton, the address is probably that of his practice, then run by his son.
