Looking for gggrandfather

Howdy,

I'm looking for the parents of my great, great grandfather. His name is (Rafe Turner).

Below is the information I have thus far.

*My great grandfather was Frank Riley Turner, (Rafe Turner's son). The earliest census I have on him is in 1900 under the name Riley living with his wife and children in mississippi.

*Frank shows up in the 1880 census with his mother Amy at the age of 16, living in Alabama.

*Frank is also in the 1870 census living with both parents, (Rafe & Amy) in Alabama at the age of 6.

Rafe's parents are the people I'm looking for.
