Leanne, Fron the info you have given I would bet that your line is Alexander-Wesley. With your father and grand father being born on Beech Fork it is almost a cinch. I know of no descendant of Joseph that settled in what is Wayne or Cabell County.
I have no info that I can find on this Alexander but will go through all my files and see if I have anything to help you.
As for Joseph I made a mistake in my book if that is where you got the info. The Joseph I am showing with children on page 738 should be Joseph Jr. I have worked on a correction for this since 1990 but have not been able to find supporting info.
