Question

How can a man who was married less than 1 year father 7 children

Answer 1

Ancestry sources have no death date for James, probably his marriage date became entered as his death date in error. This is not unusual, often we have to double check these possible errors.

And i found at least two births of children in the Mendon vital records as late as 1711 so the 1703 death is definitely incorrect.
