As the original requestor who wanted only traditional songs has apparently been satisfied, it might be a good thing to add some of the more recent ones for others who might stumble onto the thread.

A start would be to note that "Johnny Be Fair" posted by John P at 28 Nov 03 - 08:06 AM is exactly the "plot" of "Elma Turl" popularly performed by Mike Cross. I'd rather suspected an "older origin" but must have missed this thread when it was fresh. Another old thread recently brought back up gave a writer - not Mike - but I've lost it.

Another Mike Cross song, I think called just "Bill," (perhaps Bill's Funeral?) has a verse describing how Bill "burned his brothers business, and ran off with his wife," but I'm not sure ... ... do in-laws qualify as incest(?).
