Regarding John Winslow, we may have something put together within the next few days or so, and will post a notice in the Winslow Gen Forum. Besides the Chilton Mayflower book, Stratton also has much on him in his Plymouth Colony book.
Regarding the Winslow Gen Forum, I can't believe it has virtually nothing in it, and appears that many postings may have been destroyed or lost. I know that some months back I posted that we had revised/updated the Wikipedia article for Edward Winslow (d.1655) and its not there. The Winslows (sort of) come into my ancestry through the White family. The mother of my ancestor Mayflower passenger Resolved White, Susannah, married as her 2nd husband in May 1620, Edward Winslow, as his 2nd wife, both spouses having died early in that year. Their wedding was the first in Plymouth Colony. And by that wedding, Edward Winslow became the step-father of Resolved White and his brother Peregrine, who was born onboard the Mayflower in the harbor at Cape Cod. In the Winslow Gen Forum, you will see a recent posting about the Wikipedia article for Josiah Winslow (d.1680) that we recently revised and in research along the way found that both of the parents of Josiah's wife Penelope Pelham were descended from King Henry II which has been documented by noted genealogist Douglas Richardson. So if you know anyone related to Josiah and Penelope advise them of their royal ancestry and they can contact me for documentation on that as I have Richardson's Plantagenet Ancestry which has their Pelham and Waldegrave lines. http://en.wikipedia.org/wiki/Josiah_Winslowhttp://en.wikipedia.org/wiki/Josiah_Winslow
