I have just found out about William from a newspaper cutting I found whilst researching someone else and found out they lived at the same address in Atherton. I know he definitely lived in Atherton/Tyldesley, Lancs my GGrandad I think, was his brother, that has still to be determined though. He won't have been born in Cowpen, as far as I know he was born in Wales. Certainly that is where the family came from.
