As noted on my website, the father of the 'author' of the one in the Levy collection was scheduled to sing the song, in English and Irish, in a Dublin concert in the 1770's, unfortunately no 18th text seems to have survived. Sidney Owenson's (later Lady Morgan) isn't a very good text, although it appears to be the earliest extant. Incidently, her text and tune appeared originally in her book of 1805, 12 Original Hiberian Melodies, (close enough if not exact).
