↑ Based on the baptism record saying age 16 last August, several sources, including Bond, Barry, the Newton Genealogy, the Wentworth Genealogy and the Tozier Genealogy, fix Mary's birthday on 16 Aug 1693 as if it was recorded that way. No such birth record has been found in the published Watertown records. This appears to be a misreading of the baptism record. All that indicates is that she was born sometime in the month of August, with no specification that it was on the 16th.
