Looking for Informaton on Randolph Perry Hill

Hi,
I am searching for new information on my GGGUncle Randolph Perry Hill who married Julia Ann Cannedy who was born @1832 in Tennessee and Randolph and Julia were married 1853. I have very little to go on, it has been this way for several years now.
I know they had the following children: Walter, Etna, Henry, and James Perry Hill.
I have rattled my brain on Randolph hope someone can shed some light. thanks very much
