The Where Dead Voices Gather blog quotes Lunsford as saying:
The title of this spiritual is "Dry Bones." It was known in our section after the visiting of a great Negro preacher who came to that section, was a powerful pulpit orator and a devoted man, and his name was Romney. And he preached a sermon on the "dry bones of the valley." I first heard this sung by Fletcher Rhymer in the community near Alexander in Buncombe County, North Carolina.
This seems to be a reasonably good basis for treating this composition as public domain.
