Just our of interest, if we're going to attribute age to endings of Barbara Allen - "In terms of endings, from those in Bronson (215 versions) and other collections which have something approaching full texts, 10 just say 'take warning' but, of those that follow the burial ending – with roses and briars growing from the graves to the top of the church and there entwining in a true-lovers' knot – 6 don't specify which grew from which grave, but of those that do, 49 attribute the rose to William and the briar to Barbara, while only 9 do it the other way round - the folk tradition makes its own value judgements and recycles motifs at will!"
