Jim Krause, your list of tunes that all fiddler know is very interesting. Surprisingly narrow range of time and space where and when they comefrom. I know it's incredibly difficult and controversial to discuss the origins of folk material, but I doubt if many would disagree with guesses that Soldiers Joy, Fishers Hornpipe and the Sailors Hornpipe are English, that Miss mcleod's Reel is Scottish, and that the Devil's Dream is either English or Scottish. And that all those tunes first surfaced in the period 1750-1800. What is nice is that they are all very wellknown in Britain still, as well.
( Just to cover myself, yes I do know that the Fisher's Hornpipe was written by a German, but given that he was working as a musician, and writing in an English idiom for the English market, I think classifying the tune as English is reasonable in terms of usage).
Your list is a bit in conflict with the previous poster's analysis that the source tunes came from Scotland, Ireland Wales and Man. Certainly all those tunes became current in Ireland , Wales and Man. Of course it's technically possibly they all originated in the Isle of Man or Ireland or Wales but stylistically, and given the dates, I'd say England should certainly be included in the list.. .
