Thank you very much for posting these, Jim!
The first version from Peggy Delaney is very interesting, it's like a missing link between the Newfoundland version "Annie Franklin" (even the name is very similar) and Tom Lenihan's Irish version.

I think that the existance of Peggy Delaney's Irish version with that ending verse makes an Irish origin for Lenihan's version more believable.
