From Reading VR we know there are two people named Jonathan Parker who are possible husbands for Ann Flint - Jonathan, s. Thomas, Nov. 4, 1678.and Jonathan, s. John, July 18, 1681.
One of these two married Mehetabel Bancroft, Jan. 2, 1699-1700. Since she died in 1703, both are possible husbands for Barbery Elseley, Oct. 15, 1706 and Ann Flint, Dec. 26, 1706.
Because of the spelling of Jonathan in the records for the marriages of Mehetable Bancroft and Ann Flint, I think they may be the same person.
Any help would be greatly appreciated in differentiating these two.
The other Jonathan may be Jonathan Parker
