Searching this list, I see what looks like unanimity that John Parkhurst married Abigail Garfield. Likewise, in most published sources. While I agree that his wife was Abigail, I cannot not find reference to a single fact that shows her surname was Garfield.
The Abigail Garfield b. 1646, daughter of Edward and Rebecca Garfield, is very likely by reason of age and location the person who married Joseph Gleason of Sudbury, and is called Abigail Garfield of Watertowne in the marriage record. Also, the Parkhursts did not name any children after Edward or Rebecca Garfield, Abigail's putative parents.
All this leads me to ask, what is the basis, outside of quoting somebody else, for thinking that John Parkhurst wife was Abigail Garfield, and not some other Abigail? Is there any hard evidence?
