In my files I found documents that Thomas George Keylon, son of Benjamin, submitted to the LDS Church about 1918, in which he calls Harriet Renfroe his first wife, and shows her birthdate 15AUG1848, and death date 01MAY1906. It also lists his father-in-law as John Washington Jackson, and I have info from another researcher that he was married to Mary Catherine Jackson, so it looks like he married her after Harriet Renfroe Keylon died. He also lists a George W. Keylon, b. 1863, died 1889, as "nep.", which on this sheet means he, Thomas, was nephew to George, which would make George (the one on the 1880 Census)a child of Thomas's brother William Emberson Keylon or John Asbery Keylon, since brother Wright Keylon (on this sheet) died in 1863. Looks like I was wrong in stating the Wright who died in `1863 was of the older generation.
Have I totally confused you now?
