Thanks for all of your information! And thanks for your sugesstion to look into the estates of these Duvalls. It is my understanding that no will has been found for this Lewis Duvall. As for this John Miles Duvall, it seems to me he and his wife Margaret move to Bee Springs, Edmonson Co/Grayson Co. to live with Elizabeth Ricketts Duvall after Jacob Duvall passes away. I'll try to find John Miles Duvall's estate papers in one of those counties.
