Thanks for posting, Richie. Interesting to note that Robb's text, though in many respects similar to Child 2A, ends on 'Come to me and ye'll get your sark' (as per the 'Cambric Shirt' strain) rather than 2A's 'My maidenhead I'll keep', which belongs to the 'Elphin Knight' narrative.

I'm still interested in whether the fact that both the Knight and Mistress Nell are to be found on a hill might be coincidental or part of a sequential process.
