[Plymouth Register]
William Harlow married to Mary Shelley the 25 of January, 1665.
[According to Source:Stratton, Eugene Aubrey. Plymouth Colony, Its History and People 1620 - 1691 this is 25 Jan 1665/66, which would be the expected interpretation for an old style date, but it is recorded in the part of the register that deals mostly with 1664, and not in the part one would expect for 1665/66 (which is on p. 31). Daughter Hannah was born Oct 1666, which would be almost exactly 9 months after Jan 1665/66, while William's previous wife died 4 Oct 1664 leaving 7 children, the oldest being 12, and William would probably have needed help. Neither date seems to be explicitly contradicted.]
