Thanks, Malcolm.

It's worth quoting, too, Dennis Smith's 10th verse:

I wish I was in Spenservania
Where the marble stones are as black as ink,
Where the pretty little girls they do adore me,
I'll sing no more till I get a drink.

If Ingo is England (which I suspect), then Spencervania is Pennsylvania by the same logic.

"Marble sones as black as ink," a geological statement, is interesting; particularly when one refers to the Irish song, "Carrickfergus"...

And in Kilkenny it is reported
On marble stone as black as ink,
With gold and silver I did support her
But I'll sing no more till I get a drink.
   
I would guess that somewhere in Nova Scotia there was once a particular Peggy Gordon who disappointed a young man and that the song, "Peggy Gordon," with all its floating verses coalesced around the first verse.      

All the best,
