I am not certain of which generation of Benjamin Epperson exactly that you need assistance.
A Benjamin Franklin Harrison Epperson was the only son of his Father Benjamin and mother (forgot her name for the moment), who remarried a Wiley B Foster and they, I believe are to be found in the Coal City cemetery near their daughter who married a Renick.
The younger Benjamin married Emma Johnson, daughter of John Johnson and (his second wife) Nancy Crayton. This Benjamin and wife Emma wandered about through Kansas, Iowa, and Missouri to end up in Vernon county Missouri near Emma's younger brother Wallace C Johnson (my G-GFather) and her Mother Nancy.
I have retrieved Death Certificate digital images for Benjamin and Emma from the Missouri Sec of State files and those documents indicate that Benjamin and Emma are buried in "Park" cemetery, presumed the one in Vernon county, but as yet they are not listed on findagrave.com (11,000 internments, the volunteers probably as yet have not found/photographed the graves.)
