In 1931, H. H. Fuson published a version of "Ten Thousand Miles from Home," in "Songs of the Kentucky Highlands." Several verses are identical to those sung by Reneau in 1925, if the copy of the Fuson version, B in Lomax and Lomax, ABFS, is accurate. I have not seen this book, so I don't know if there is evidence of the 'Danville girl' before Reneau's recording. The Lomaxes credit version B of "Ten Thousand Miles From Home," which includes the Danville verses, to Fuson's book, but apparently in a letter to Seegar, the Lomaxes said their version was a sort of compilation. Fuson's book, printed in England, is rare, but perhaps someone can check the song and comments in a library.
Doc Boggs recorded "Danville Girl" in 1927, Brunswick 132.
