I have son Jonathan b. 25 Oct 1737, and dau. Johanna b. 6 Aug 1740. I can't vouch for the accuracy of that info, as it is from The Book of Dow, and not a primary source, but the book cites Salisbury records as the source. The marriages are listed there as follows:
Dinah Severence (Severens in rec) 6 Jan 1713-4
Mary Challis ca. 1719-20
Elizabeth Simonds 3 Feb 1739
Book also says the Shaw Genealogy not clear on who Hannah was.
Email me if you are interested in having copies of the pages with this info.
