Philippa,

O Lochlainn cites his Mother who came from Limerick as the source of the tune and some words. The words he published seem to have been a composite version from a number of sources including the Journal of the (English) Folk song society and from ballad sheets. He also quotes some lines from his Grandfather who died in 1890. No other dates given in the notes. Its in the first volume of his book which I think was frist published in the 1930s.

Christy Moore's version of the song is on his first solo LP after leaving Planxty which is simply called Christy Moore (c 1974). He may have re-recorded it for North & South which was a much later album - I'm not sure.
