To Nathan,
Westphalia is part of Europe that as far as I know has sort of passed back and forth between Poland and Prussia/Germany over the years. Texas also boasts the earliest Polish American settlment in a place called Panna Maria(The Virgin Mary). I have heard Polish words sung to this tune that go on about a woman asking a doctor when is the best time for loving. that's all I can spew off about the song except that lots of early settlers in America were not Irish/Scotts so not all the old folk songs are derived from those sources.
