The Letters to Herndon from Dennis and John "Rail-Splitter" Hanks: http://www.gwyneddfriends.org/herndonmain.htmhttp://www.gwyneddfriends.org/herndonmain.htm After reading these letters it appears that the mother of Nancy Hanks was the Lucy Hanks (spinster) accused of having a child out of wedlock in the court records of Mercer Co., KY, 24 Nov 1789 (five years after Nancy's birth and more than a year before her marriage to Henry Sparrow, April 03, 1791, in Mercer Co., KY).
Sturgill hypothesis Through a William Hanks m. Hester Mills line, so discredited by the y DNA evidence.
Lincoln Co., NC y DNA shows this line is unrelated to Nancy Hanks, mother of the President.
Maryland line some oral history claims of relationship in the Bedford Co., PA offshoot of this line. Consistent with the y DNA evidence (not proof, just not eliminated)
The Shipley hypothesis originated with Charlotte Vawter, a great-great niece of Richard Berry. There is a strong likelihood that Nancy Hanks grew up in the home of Richard and Rachel (Shipley) Berry, but no evidence that Nancy was related to them other than Mrs. Vawter's recollections, some of which can be demonstrated to be false.
