It seems as if we are all dancing in the same area. I too have been searching for the roots of William J. Massengale (sometimes spelled Massingale). I am almost convinced that William J. must have been the grandson of Abraham. Abraham had a house full of women living with him, along with one non-white, non-slave. Could this have been Abrahams wife? Could she have been American Indian? Is that why Abraham's daughter's were all still living at home instead of being married? Is that the reason for the migration? There are other clues as well. A close neighbor and family friend named Dewberry arrises. He named some "supposed" Massengale children in his will. William is not named, he could have been born afterwards...but one of his children's middle name is Deberry(?) A clue? Who knows?
We need a relative from NC to research this for us. It is indeed a mystery.
