(strange 2 children 1812 unless there are 2 James/Marys around)
Cant find anything for ISAAC to a James/Mary unless he was not their child, There are possibles.
One illeg born to a Mary Berrisford
This one seems to have married 23 Nov 1846 and names his Father as Soloman MELLOR.
Interestingly a Anne Edge* is a witness.

I am doubtful your James was the one born 1783 Alton.
