Hi Harry, thank you so much for information about the Micheldean congregational churchyard, and for popping in to the burial ground.
As S and S were very much "chapel" it is likely that they are down there, but unlikely that there are headstones as there is a "thing" in the family about these; I had done several "wild card" searches but nothing came up.

I have started doing some more research on this, so hopefully may eventually come up with something. Any relevant suggestions always appreciated.

Regards, Celia
