I Just added son John Thornton to James Thornton, thornton-1705, they already have a John Thornton with different birth date and child. My main source is 100’s of Families from the Eastern Shore, from Charlemagne to the early 1900’s free source at Virginia Library: http://espl-genealogy.org/MilesFiles/site/p505.htm#i50433.
