According to "New England Marriages Prior to 1700" ( by Clarence Almon Torrey, Genealogical Publishing Co., Inc., Baltimore, 1985), the date of this marriage is 19 March 1657/8. Boyd Scott Remington has 19 Jan 1658. The town records probably say "the first month," which at that time was March. An online transcript of the Rowley records has 19 June 1658, as does Carl Boyer's "Ancestral Lines Revised.".
His date of birth is noted as "26 10m 1663." Since March was the first month of the year then, I interpret this to mean December. Some online genealogies have his birth date as 6 Oct 1663, but this is probably incorrect.
The date of Jonathan's death, as well as this list of his children, came from the Rootsweb database of Debora Heath: jlheath@netzero.net
