Note that this Matthew in 1851 Census is unmarried so it cannot be the one who married Mary Wearn ??????? It would also appear that this Matthew and Samuel were brothers and that the Eleanor in 1841 Census was their mother???? There were a couple of Matthews born that are registered in Family search which would have Been the correct age to marry Mary.
There appear to be a few Mathews born that could have been the husband of Mary Wearne.
