A survey of the head stones in St Mary's at the Walls churchyard was undertaken by Gillian Brown, Mary Coe, Anne Polley, Noreen Proudman, Jean Roberts, Rosemary Yorke-Moore, John Mallinson and Freda Nicholls in 2001, and compared to the survey by F.A. Crisp in the late 19th century.<1> 223 graves remains. The earliest identifiable grave is no. 96 (Crisp no. 140) with the date 1707. The most recent burial was in 1967, grave no.122. An area in the North East of the graveyard is the site of 47 cremation burials. The earliest grave in this group is dated 1931 and the latest 1998. The total number of headstones recorded was 163 Of these 73 could be identified by reading the inscriptions. Crisp recorded 161 headstones and was able to identify 157. The discrepancy between these two totals is accounted for by the fact that two stones were placed after the time of Crisp's survey. 55% of Headstones can no longer be identified.
