Richie,
Flanders' notes hopefully will clarify the situation. These 2 ballads are not ones I've had cause to study. I used to have a book 'Yarrow, Its Poets and Poetry' which contained a whole gathering of literary poems inspired by the Yarrow and the 2 ballads. As I'm not interested in literary ballads I gave it away many years ago.

By sheer coincidence, and I don't get out a lot, someone sang 'The Dowy Dens' at a folk event I was at last Saturday.

This sort of thing is happening far too regularly! Spooky!

I'll get the stuff off to you ASAP. I assume you've already checked the Roud Index.
