Dr.Fountain of Smith Co.

Dr. Fountainof Smith Co. married my grandparents in 1877 at E,H.Barbers.
I believe he was a Methodist minister.I am trying to locate the church where he may have pastored,as I believe my Cox family may have attended his church. GGrandfather, Stephen Franklin Cox served in the church as District Steward, and was Distrist Conference delegate several times.
will appreciate any help.Emma Cox Odom
