Thanks once again for your help Jeff. I hadn't appreciated all the mining activity in the Forest until now. My ancestor was a yeoman so I hadn't come across the term 'gale' before. I can see on the OS map the kind of area we are in although the exact location of Stoney Stile or New Stoney Stile is still a little elusive. It makes sense that my ancestor moved someweher near Coleford though.
