Unfortunately our OP here has not been able to acknowledge the information found as yet.
However I do note in JM's findings from the submitted information-
Elizabeth (1827-1916) (m Rainham),
JM
If this is the correct Elizabeth, her birthdate would make it very unlikely she could be the mother of the children listed to her in the years attributed.
The age given at death is 73 in 1916.
