Lee Sexton does a haunting version of "Danville Girl" on his "Who Mule" recording for Appalshop. I took the title to refer to Danville, Ky., as Lee lives in Linefork, Kentucky, and would guess that the lineage of his song goes back thru Roscoe Halcomb (one of his relatives), to Dock Boggs and, judging from comments here, to Mr. Reneau. John Cohen of the New Lost City Ramblers collected extensively in area and could have picked it up here -- then again, the NLCR collected in a lot of places.
