When I asked my initial question I knew nothing of the history of OS maps. I thought someone might have a key and be able to provide the answer. I now understand that is not going to happen. Thank you MollyC for all your help with this. The reason for my question is related to a family history and the chapel. The family were involved with the founding of the chapel and in the very early days the graveyard did not exist. In fact, the chapel building as such did not exist entirely in its present form and it is believed meetings began in the nearby farm house. Several histories have been written for the chapel in which there are references to early burials. No-one now knows whether those early burials took place in the location of what is now officially the graveyard or near to the farm house where the early meetings took place. All is known is that those early burial were carried out before the official commissioning of the current graveyard, hence my initial query as to whether or not that shaded area might indicate burials. With regard to the family history, we are trying to establish who owned which fields around the chapel. Wills aren’t specific enough. I was hoping other sources might help but I am not sure what I need to ask for or even if such sources exist! We know the fields must have changed hands from time to time but surviving documentation appears to be sparse. Thank you to everyone who is contributing to this discussion.
