Richie,
Brilliant and many thanks. I hadn't linked the 2 American versions either with each other despite having the same title, nor with Gleanings, nor with the garland ballad which is simply known as The Northern Lord and was widely printed. Most copies are 18thc but Pitts also printed it. Again it was printed by my local printer John Ferraby. There is a copy on the Bodl. Harding B4 (16) which has 49v but I have record of a copy with 56v.

I'd say Shakespeare is the more likely direct source for this one, whereas the other probably came directly from continental tales.
