See the "New York Trader" in the DT and threads. The threads will lead you to other names like Captain Glen. The song is known from 1794 if not earlier. Many broadsides of the New York Trader are in the Bodleian Collection. Search at Bodleian Collection Also there is "The Cruel Captain" (captin- sic) at the same site. I think enough variants to satisfy you are already posted here at Mudcat.
