>>only one traditional version calls him 'Woodstock'; Richard Hartlan's (South-East Passage, Nova Scotia), recorded by Helen Creighton and printed in Songs and Ballads of Nova Scotia (1933)<<
Maybe this is just a coincidence, but the first singer I remember hearing perform it as "Woodstock's" courtship was also Canadian. That was Joanne Hindley-Smith, who gigged fairly regularly around the London clubs in the mid- 1960s, well before the upstate NY mud-fest made Woodstock a household name.
