I photographed and indexed all legible gravestones in this graveyard. If a person buried here is not listed it is either because the stone is not legible or because the stone has disappeared. It is common for many of the gravestones of persons listed on the burial register to have disappeared either through damage or neglect or through removal for improvements such as paths and paving. You could try contacting the church or the local family history society to enquire if a plan of the gravestone locations in the churchyard exists that has been cross-referenced with the burial register. This is quite often the case and if the gravestone exists but is illegible this may point you to the location.
