From CWGC Good morning Clive I attach a Cemetery map and have circled the grave site for JD Constable(but from the sound of your enquiry you have already had this?) On looking on our data base it states that the grave is unmarked as relative refused a headstone, but the Grave number is 96922 it is of level turf two back and 6 right of CH to Carter.
