"Paddy's Lamentation" or "By The Hush, M'Boys" appears in the first volume of Edith Fowke's "Folk Songs of Canada". It is also in "The Penguin Book of Canadian Folk Songs", which contains so many of the songs from Edith Fowke that she should have received royalties.

Ms Fowke collected "By The Hush" from a vigorous old logger, O.J. Abbot of Hull, Quebec. If I recall correctly, that version is the source of most North American iterations of this song after 1950.
