The ballad is timeless and has no boundaries
CLARE VERSION

Peggy Seeger's father Charles made an extensive study of it's history and tunes and issued an album of 31 variants- my personal favourites being the first by I N Marlor, Boyd's Cove, NC and the last by black Texas convict, Moses 'Clear Rock' Platt
The notes of the Library of Congress albums are usually available for free download from Smithsonian should anybody be interested
