Burial Ground About 300 Friends are buried here including William Dewsbury (1621-1688) an early Quaker minister, who was imprisioned for his beliefs in York and Warwick. Whilst in Warwick gaol he was looked after by his granddaughter Mary Samm who died, aged 12, or gaol fever. Both are buried here. Please note the simplicity of the two remaining headstones which have been placed on either side of the French windows.
