The Nancy HANKS who married Thomas LINCOLN was, according to Adin Baber's "Nancy Hanks The Destined Mother of a President" published 1963,page115 , ---most probably the Nancy daughter of Abraham HANKS and Sarah HARPER HANKS of Campbell Co. VA.Nancy's Paternal grandparents being Luke I HANKS and Elizabeth (?)HANKS of Northfarham Parish, Richmond County VA, andNancy's Maternal grandparents being George HARPER and Elizabeth SHIPLEY HARPER.
The Nancy Hanks,b.Hampshire Co. W.VA,which you show as daughter of Joseph HANKS and his wife Nancy SHIPLEY HANKS would have been the Nancy who mothered Dennis Friend HANKS and married Levi HALL.(Joseph was another of Luke I Hanks' sons, and therefore a brother of Abraham HANKS)The two Nancy's both born 1784 were cousins to each other.They are both buried in Spencer Co. IN , along with another of Joseph's daughters, the Elizabeth HANKS SPARROW.(see page 92 of Adin Baber's "The Hanks Family of Virginia and Westward" copyrighted & printed 1965).
Many early historians (Carolyn Hitchcock and others) confused these two Nancy's,quite understandably, with them being the same age and cousins, both named Nancy HANKS.
Mr. Baber's research shows, very convincingly and thoroughly, that the Nancy who married Thomas LINCOLN and produced Abraham LINCOLN (the future president) was the daughter of Abraham HANKS.It seems Thomas LINCOLN's father was also named Abraham LINCOLN,and the young president to be was named Abraham after each of the two grandfathers.
All these similar names have resulted in many confused genealogists!(Myself included, until Mr. Baber clarified it - and hopefully I have understood his writings, and am conveying the information correctly here)
The SHIPLEY, HARPER, HANKS lines intermarried,in many ways, adding to the confusion.(Including, apparently,the Mary SHIPLEY, dau. of Robert and Rachel, who you show).I have not done original research on either the HARPER or SHIPLEY or LINCOLN lines, and appreciate your nice outline,but wanted to clarify the Nancy, mother of the president, parentage for HANKS researchers.MTM
