Wow... The Freeman family genealogy is quite a Gordon's (?) knot. George Ernest Bownman tries to untangle mistakes made by previous researchers in "John Freeman of Eastham and Harwich," in MayFlower Descendant, volume 33 (1935), page 100 on.
VERY MUCH recommended reading for anyone descended from both early Freemans and Watsons. Sheesh.
Members of the New England Historic Genealogical Society can access digital copies of this and other journals. See www.americanancestors.org. Membership is affordable, and any researchers of colonial New England ancestors should join. Their digital holdings are phenomenal, and include much that is not available through a standard Ancestry.com subscription.
