I looked around Rehoboth Welsh Independent Chapel and Horeb Baptist Church. Rehoboth looked good from the entrance, but they were the more recent gravestones. The slightly older ones were at the back, up a steep slope and around the sides. Many were broken, toppled or weathered unreadable. There was no sign of a Walters. Having posted, I then looked again and noticed Horeb Baptist Church, which technically is closer. Now it is closed and crumbling. There is a small graveyard, with fewer damaged stones; and again, no sign of a Walters.
Although positioned between Five Roads and Furnace, in farming 35 Acres, there would be access to the road behind that takes you to Swiss Cottage, Felinfoel and Dafen. At the time, I think it was a track rather than a road. It would seem they married in Dafen. That may be where they worshiped and are buried. It is a fair distance from the farm, but I have relatives in the mid 1800s, who travelled similar, with some even further. In Dafen, there are two possible places with graveyards, and more still in Felinfoel.
Also, some children are not accounted for in the Census records. For there to be a Grandson called Walters, it suggests there is a son.
