As far as I know Deborah had no children.
According to a portion of the will provided by another Safford researcher John's son Joseph and Gideon were executcrs. He leaves to his wife Deborah all movable estate. To three living daughters, Marcy Tracy, Elizabeth Whipyrill and Margaret Bingham, Charity Raseboone, eldest dau of dau Hannah, and Zipporah Haskell, eldest dau of dau Sarah, the gr-dau to share equally with their aunts.
No mention is here made of son John, born 1687. No mention is made of him as being buried in the Safford Cemetery, either. Marcy is probably daughter Mary, b 1697, Elizabeth, b 1700, Margaret, b 1703. Daughter Hannah had evidently died by this time as evidenced by the will, same with Sarah, b 1694. With Gideon and Joseph as executors, that makes 7 listed. Only John is not listed.
I do not have too much information on this part of the Safford family. I think that no one can say for sure just who was married to whom. It's very confusing and conflicting.
