Oh yes, Nancy-Jean! Good thought. Which reminds me, what about Dan and Bonnie Milner, who have recorded an album based on songs collected by Nancy-Jean's grandmother, Helen Hartness Flanders. I can't quote specific ballads they sing, Dan's primary focus is Irish music and Bonnie's is maritime, in fact right now the only thing that comes to mind is Bonnie singing "Dark Eyed Sailor," but still I suspect they should be added to this list.
