Then how do you account for "Slane"? Many of the place names attached to tunes were where there were first recorded by the collectors, hence "Monksgate" for "Our Captain Cried..", "Kingsfold" for "Dives & Lazarus".
I just know this is going to put some noses out but not every great tune with an Irish name or lyrics came out of Ireland. With the Irish visiting England as mercenaries, sailors,navigators, nurses, programmers for 800+ years (and for a few hundred before that as saints and scholars)it would be surprising if they didn't take a few songs and tunes home and file off the serial numbers.
