We know Sam Harmon's version (above) because it is the same as his wife's (Henry collected it) which came from Council Harmon, his grandfather.
We know Maud Gentry Long's version (above) came from her mother Jane Hicks Gentry- only Sharp included only one stanza of Jane's text with the tune. Smith lists it but I can't access on google books- anyone?
