There may or may not be an obit as in my experience obits of earlier deaths are hard to come by.
Have you tried contacting the Roane County Courthouse? I know they can look up and send you copies for a fee.
Also maybe try wvroane.org (the historical society website). Maybe some one there can help.
Good luck. Sometimes information comes easy and sometimes hard. Just today I found a small tidbit of information regarding an ancestors death that I have been chasing for a decade.
