Jim,
regarding "The Brown Girl / Sally The Queen / The Sailor From Dover" (Child 295 Appendix).
Eddie Butcher used to sing a song, "Down by the canal", that had the doctor verses from Sally in it.

The recording is available here, including a transcription:
Eddie Butcher - Down By The Canal

I don't know whether they are just stock verses that appear in several songs or if this is proof that the "Sally The Queen" ballad circulated in Ireland but I thought I'd let you know.
