i saw your post in the doty genforum and have very little more to add and what i have comes from the pilgrim edward doty society printing of the first five generations books of edward of the mayflower
what you have as far down to mary(matchey,matchie) doty is probably correct.
the entry in the 5 generations book says she was b. 1744 ca in somerset conj, died after 1829she m 1st james bishop. they had one dtr, harriet. no further. she and james were m. ca 1773. it does not say if he died or they divorced. she m 2d joshua martin before 1780he was b. 175l, died 25 aug 1815, age 64. they lived in martinville, nj.they had five children: absalom, john, b. 1785 who m. maria todd and they had no children; james, samuel and polly(probably Mary)
at the start of this entry they call marie(motchey)
there is a folow up on all of the children except what is already written about john.
all of the five generations books are available thru the society. each child has his/her own book
i can give you the other children and their families but don't know how far each is carrid out astime is not available just now to go thru to do the entire line.
i would be willing to help further if you can wait until i get back from the lake in wis sept 13.
