Fisher, John and Elizebeth Boylston, Apr. 6, 1658.
↑Source:The Fisher genealogy : record of the descendants of Joshua, Anthony and Cornelius Fisher of Dedham, Mass., 1636-1640, p. 17, gives the marriage date as 6 Apr 1656 (instead of same date in 1658). Obviously, all things equal, one favors the primary source over this secondary source, but also, since the first child, Elizabeth, wasn't born until 6 Feb 1658/59, 10 months later than the 1658 date, and Elizabeth was born in 1640 and only just came of age in 1658, it is extremely likely that the date in the Fisher Genealogy is an error.
