The book about Blackburn, to which I was referring, was dated about 1900. My brother,Stephen, has it.
As to religion, my grandparents were married in Blackburn in about 1906 at a Baptist Tabernacle. This was,I think, a Particular Baptists congregation.
Thank you for all of your help. My next task will be to track down the family of Obadiah Chew.
All the best,
