Yes, I've certainly heard that Anne Briggs wrote it. As I recall the tale was that became widely attributed to "Trad" quite early in the revival, Anne never asserted her authorship, and many performers (including Gaughan) helped perpetuate the misinformation.

However John Moulden's source suggests otherwise - assuming that 1893 source includes the contemporary words as well as the tune; could you clarify, please, John.
