Hello
The four marriages that we have mentioned above, for Thomas Moss are ...
1838 (3rd quarter) to Susannah Cartwright at All Saints, Wigan
1855 (3rd quarter) to Dorothy Fletcher at All Saints, Wigan
1868 (13th January) to Esther Mawdesley at St George, Wigan
1887 (4th quarter) to Jane Atherton at St Catherine, Wigan
If it were possible for someone in Wigan to check the registers for these marriages to ascertain if the same father is specified for Thomas on each occasion, it should help to determine if all the census entries refer to the same man or to more than one man.
A more expensive option would be to purchase some of the actual certificates. If the 1838 and the 1887 marriages have the same father for Thomas, then it is almost certain that those in between will be the same.
