Haven't got Gregory but will be looking for a copy shortly.

The closeness to 'Cruel Nymph' is curious and I'll be analysing this in detail later today.

If both the author and collector were not aware of Child 295 and seemingly 73 I wouldn't put much weight on their authority.

The most generous ascription I can give at the moment is that the family's perception of how far back the ballad goes in their family is wrong and the likeliest scenario is that their version derives from Child.
