Hi Ray.
Hope you are ok. Just to clarify for you, the first census is the 1891 for John William Hindley and the other census is 1881 and that is John Hindley, iron forge man (blind) and John William is 16 years old and a iron forge boy. The family are living at 85 Simpson St.
Sarah Bowker is Jane`s mother and her husband was John Bowker. I haven't done much research on the Bowker family.
Look forward to hearing from you soon,
Jackie.
