I just spotted this thread. James E. Bush is brother of Charles W. Bush (my great grandfather). They have another brother, William. Parents are Jacob Bush and Sarah Morris. Jacob and Sarah were divorced and Sarah moved in and later married into the Lambert household. I believe that Jacob's father is Nathan Bush but I can't substantiate that other than to note that a Jacob is listed in Nathan's household in the 1850 Greenup census - Jacob's divorce was in process (or possibly over) at that time. Hope this helps.
