I found the family in Cocke County in 1860 with one child and Sevier County, TN in 1870 with 4 children.Anna Fine was living with them by 1870.Robert died in May 1882 in Sevier County, TN.Their children matched the names you listed- William, George, Lou Allen, and Mack. Children of Robert Sneed and Mary "Polly" Fine: William SNEED b. abt. 1860, m. Minerva Carr George SNEED b. abt. 1864, m. Ellen ROMINES Roda SNEED Elizabeth SNEED, b. abt. 1867 Mary SNEED, b.
