Many thanks for your replies, chaps, it took you less time to reply than it took me to work out how to use Google Streetview - it was one of those things I'd been meaning to do for some time but never had. I've now had a look at 112 Albert Drive but I don't think that it's the same house, however Albert Drive and Gannock Park sound good areas to start looking.
Bri, my grandfather was Sam Jones, Bethel. One of the Ty Bethel Capel (should that be Ty Capel Bethel ? I'm sure someone will put me right.) family, who between them were chapel keepers at Bethel for more than 100 years.
