I heard this performed in Scottish Gaelic by a singer named Kennedy at the Spencertown Academy in New York State, probably back in the 80s. He explained that this was the "wife runs away, husband goes after her, captures her and her lover, kills him, locks her in a hut for the rest of her life" version from which the modern Gypsy Rover descends. He had a very haunting voice, though I couldn't follow one word of the lyrics.
