It does not appear that any of the marriage records name the parents, so this may be a difficult case. I think the best we can do is "a preponderance of the evidence." I put a few notes on some of the profiles. I'll try to dig deeper tomorrow. If you look on FamilySearch, they have a whoooooole bunch of children attached! The Elizabeth who married John Maynard only has one child which seems unlikely since they were ostensibly married 30+ years. Another Elizabeth was married to Joseph Kimball and possibly also Anthony Spears. I haven't looked at the dates yet to see if that is even possible. Maybe there are land records or something with names on them. There are some notes, but they look like cut/paste and are hard to understand.
