Since he is not listed on Find-a-Grave website in Jackson County, WV, I would suggest you go to their county website and put a query out. Perhaps someone can do a look-up for you in their cemetery publications. I did a Search for Miller on their website and there are numbers cemeteries that come up with Miller burials. Ripley is the county seat for Jackson County.
You may have to join their mailing list to put a query out.
