Long shot my Johnson line is on the Tn & Ky border Cumberland County Ky and Clay (Overton) county Tn. See www.familytreemaker.com/users/j/o/h/William-C-Johnson You have many of the same family names. Possible your Joesph could be an older sibling to Sarah born circa 1839. She was the oldest in the 1850 census. Good Luck William C. Bill Johnson
