John W. JOHNSON married Mary Ann JOHNSON 25 Oct 1859 in Clarke Co. AL, She was the daughter of James M. JOHNSON born about 1813 in GA and his wife Elizabeth A. born about 1819 in GA. They apparently went to Clarke Co. about 1858 from Conecuh Co., AL. They were in the census in 1850 in Conecuh Co.
John W. JOHNSON was the grandson of Dudley JOHNSON born 1766-1770 Halifax Co., NC and his wife Elizabeth born about 1780 NC, but I don't know who his parents were. They apparently died when John W. was young.
