Juliana Smith has posted my article "Pilgrim Ancestors" on the Ancestry.com blog. There are links there to a variety of sites and a discussion of making a proof and establishing a case and working on a Pilgrim connection.
There is also some commentary on my own potential Pilgrim connection.
And if anyone knows anything about Clark Sargent who died in Winnebago County, Illinois, in 1847, let me know. If I can connect to him, then I have a likely Mayflower connection.
