Hi, Deckman -
Good to be in touch again.
The story of that museum is on those pages. Mrs. Jones used to live there. Towards the end of her long life (she got to be 92), she was "discovered" by the popular media and by folklorists. She appeared on network radio shows, spoke to songhunters and to pretty much anyone who went to the trouble to seek her, but seems to have remained a sensible and down-to-earth type.
One article mentions that a highway runs near the crash site and there is a historical marker there.
Another mentions that she liked the song but she would not listen to it because of the last verse.
