Itr's Tom Dula, part of this comes from "The Statesville" reporting on Tom's hanging, but my source for that would be Alan Lomax who credits Frank Brown as being the collector, not so much of the song or tune but of the Folklore, Lomax & Frank Warner are both listed as sources from Folk Song:USA along with Henry in his Folk Songs From The Southern Highlands. Folk Songs From North Carolina -2 volumes of a 5 part series (North Carolina Folkloe) were devoted to the songs & lore collected by Brown.
