In case you don't know, a few years ago the Mayflower Society determined that Benjamin Doty, son of Samuel Doty, son of Edward Doty of the Mayflower, was not, after all, the son of Samuel. Their new information says:
"With respect to the son Benjamin, Doty Gen says the '...in all probability, under the name Benjamin Doughty, he m. Abigail Whitehead...' However the Benjamin Doughty who m Abigail Whitehead in Jamaica Long Island NY (license 23 Apt 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 Benjhamin Doughty, husband of Abigail Whitehead was descended from Rev. Francis doughty of Long Island, and not from Edward Doty of the Mayflower."
At the moment, however, I have been unable to find a spot for Benjamin in the Francis Doughty family tree.
