"Are these the folks sometimes referred to as The Black Irish?"

I had heard this story long ago, and it came to mind when I saw the flamenco dance in the TV broadcast of the original Riverdance. Is that why it was included?

In the Netherlands, the word for furniture is Mueblen, a cognate of the Spanish word Muebles? For a time the Low Countries were under the direct control of Spain. Coincidence that a Germanic language uses Spanish words?
