If you are trying to find the parents of Nancy Stringfellow (17 Sept 1776-13 Sept 1832)who married Elias B. McFadin on 8 Apr 1802 in Warren County, KY-read the following.
Her name was copied incorrectly about 100 years ago and has now appeared in two books:"The John Stephen McFadin Family" by Maude A. McFadin and "The McFadden Family 1700-1998" by Etta R. Otto. Her name is written very clearly in the Marriage Register of Warren County KY as Nancy Stringfield.
When this change was made-everything fell into place.
I wasted many hours of research time and hopefully this posting will help someone else.
