Anne,
Vol. 11, part 2 says (p.7): "The Benjamin Doughty who married Abigail Whitehead in Jamaica, Long Island, NY (license 23 Apr 1720) was identified as 'of Flushing, carpenter.' His guardianship of Samuel Stockton, who descended from the Long Island Doughty and Whitehead families is further evidence that Benjamin Doughty, husband of Abigail Whitehead, was descended from Rev. Francis Doughty of Long Island, and not from Edward Doty of the Mayflower." If you would like the citations that are given to support this, just let me know.
