I was there, in Stichel, in the graveyard in October taking pics !! I hadn`t seen this post then , or if I had I`d forgotten, in the intervening years !!
I would willingly have taken some photos for you, especially as I think there may a slight connection between your Gray family and my Black family. This needs more work at present as I have got so many generations with the same christian names.
However, I am hoping to go again sometime but it`s a long drive from west Wales where I live !
