"Peter Bellamy recorded Peggy Bawn accompanied on concertina in 1974 for The First Folk Review Record" ... Mainly Norfolk online site

Actually listed there as "Peggy Bann", iirc. Not the same song. In this one, the narrator is offered marriage by a rich young woman he meets "As I wandered over Highland Hill", an offer endorsed by her father, who offers him "Five hundred pound ... Likewise a piece of land", if he will marry his daughter; but he refuses the offer, as his own "jewel", Peggy Bann, awaits him at home and "My heart lies in her breast; and although we at a distance are, still I love her the best. Although we at a distance are, and seas between us roar, still I'll be faithful to my Peggy Bann, so farewell for ever more".

The coincidental similarity of the name is all that seems to link these two songs. Not even clear if they were originally versions of the same song.
