Mike, Mary's parents are assumed from documents and associations that Francis Martin had in association with Josias.So nowhere in antiquity, that I am aware of, is her name ever given except as "Mary."But it is a pretty good bet that her parents were Francis and Jean Martin.Especially since one of her and Josias's children was named Francis.
The birth dates of all of their children are assumed or guessed and again to the best of my knowledge.Their death dates are better known, at least with respect to the year.
