He lived in Wilkes County GA till 1920 census. In 1880 GA Wilkes County census he is listed as Divorced and the Lena and John are his daughter and son from 1st marriage, with mother Ester Mattox also in household. I believe the census taker mis-marked the numbers for household counted as a Ellen Tavor or favor listed as sis-in-law at age 14 or 16 should be in household above of Charles Waller. In 1900 Boston and Susan are married 18 years, so 1882. GA marriages has Boston Mattox married a Martha Glover July 5th 1874 in Elbert County. So look in Elbert County GA as well as Wilkes County GAfor records.
