Wow, this is a long thread and I didn't read it all. However, I wanted to respond to the person looking for songs that Hughill wrote were mentioned in a source. I am guessing that he was not infallible and that he indeed might have mis-remembered some things, because I went through "Landsman Hay" with a fine-toothed comb and only found mention of two of the three fiddle tunes Hughill said were in there. It's still possible I missed the third, but I really tried hard to find it!
