She will either be in the Quesenberry Cemetery, Indian Valley, Floyd Co VA, where her father is
or she may be in the Capt George Cemetery, Indian Valley, where her husband is.
Buried in father's cemetery most likely, since she died so young, and her grave is most likely unmarked or the marker unrecognizable. It's not listed on FAG for either one, but in my experience doing cemetery surveys, there are more unmarked graves than marked ones in these old places.
