Of course it's impossible as it is with many Child Ballads but that didn't stop Child from slating them, quite rightly in my opinion. By all means add it to the known versions. That is right and proper, but make sure you add in the other overwhelming evidence that makes it look extremely suspicious. I still maintain that 'Cruel Nymph' (which has 2 extra verses unknown to SBG and Child) is not part of the equation.

SBG also has previous. Look at the text he sent Child of The Gipsy Laddie which Child quite rightly rejected. He was also a known forger and hoaxer. SBG's biographers freely give this information, some of them his relatives.

Remember also Brown Girl/Cruel Nymph are also extremely rare, copies being found only in 18th century print in 4 copies. It is highly unlikely Woodridge or anyone else in his situation had access to these texts in the BL. We know SBG had access to one because he sent it to Child.

I'll investigate the Pretty Dorothy text. I'll be at the VWML on Saturday anyway giving a presentation on 17th century broadsides.
