I can see that I'm coming to this thread 15 years after the rest of ye, but I'm finding this very interesting and I can fill in some of the gaps in the story of the song I think.

Cloch corr, Uillinn, Poll a Mhadaigh and Baile an tSratha are all places on Arranmore island where R?ise lived most of her life, so 'poll' isn't an obscenity or anything, but the name literally means 'hole of the dog'. Burtonport is the nearest port to Arranmore and Rutland. It's interesting that it mentions Rinn na Feirste too, because I didn't know there was any part of Napper Tandy's story based out there.

I find it interesting that it refers to Napper Tandy, because in that case it would be telling a story of everyone beating him up, breaking his ribs, having a litany said for him, setting dogs on him, putting a yoke on him (as in the piece of a harness put over animals to pull a plough), and 'making sport' of him (which I figure must mean hunting him away). They must have really hated him if this was about him.

The Bacach S?ol bit seems like a curse on him alright.
