Robert Cinnamond isn't a name knowm to me, but googling turned this obituary:

The Ballinderry Balladeer

Interesting that he came from a weaving family, and the report makes mention of his father buying an armful of ballad sheets at Lisburn fair. Could this song have been one of them? At least this makes it less likely that the song was another of Bert's fabrications.

My own version comes from "Folk Song in England" supplemented mostly from Steeleye's version. I passed the song on to Tom Kitching but as Sugarfoot Jack points out Lucy already had the song in her repertoire. Pilgrim's Way make a nice job of it.
