In 1841
John Caig did live in Gregg's Lane. He was 45 yrs(rounded down to nearest 5 yrs), Coal Miner, born Scotland.
Also at the same entry no. were Hannah, aged ? 4 yrs., Mary, aged 12 yrs. Both down as daughters, but the enumerator has put a line through as this info. was not officially required presumably! Both born Cumberland.
Also a John Linton, 21 yrs. Butcher, and Mary Smith, 82 yrs., widow (line through). Both these also born Cumberland.
Hope this helps - looks as though he was already a widower by this time.
