That would be new and important information. However, I don't follow the line to Edward Doty that you give. This is the only information on the Doughty family on that site:
Born: ABT 1486, Louth, Lincolnshire, England Father: William FITZWILLIAM of Mablethorpe Mother: unknown
Married: Robert DOUGHTIE (b. ABT 1500, Louth, Lincolnshire, England)
1. John DOUGHTY
I can follow the Fitzwilliam line to that point, but the line ends there with John Doughty. There is no further lineage down from John Doughty. And, there is nothing there to tie John Doughty to Edward Doty.
We would all be overjoyed if you can point the way to tie these two together, since Edward Doty's ancestry is a very old riddle to Mayflower genealogists. I am hopeful that I am overlooking something on that site.
