I still have a few pages from Currents of Malice on Mary Warren, but not all that refer to her in the book. Mary had a father and sister living in 1692. According to testimony, an accused witch, killed her mother and struck her sister dumb(whatever that means)when Mary's father, for whatever reason, didn't plow the accused field for her. Mary's family does not appear on Boyer and Nissenbaum's Salem Village census in Salem Village Witchcraft: a Documentary Record so they must have lived in one of the outlying areas--Topsfield, Andover, Wenham, Watertown, or perhaps near the Proctor's where Mary was a servant. I think Sarah Warren Prince Osbourne was originally from Watertown and was the right age to be Mary's aunt so if Sarah and Mary's father were brother and sister, that would be the place to search, perhaps. I tried tracing Sarah on the FamilySearch Webbase at Salt Lake, but only got the family pedigree for her first husband Robert Prince. Perhaps looking up any 17th c Warrens in Watertown MA might be a start. So now I have confirmation that two of the afflicted girls, Mercy Lewis and Mary Warren weren't orphans and had some family, at least.
