Interesting idea, Joybell. Not much point in lumping them together as pd-trad. Good to know when the songs were written and the composer(s).
Most will prove to have a beginning, and comparing sheet music will show 'folk variant', at least in the hands of the Carter Family.

Here are the top two on that long list by Richie. More later today.
