My Dad and I watched The Lords of the Dance. A lot.
My paternal Grandfather insisted he was hidden on a ship as a little kid, got into the US from Ireland., until his dying day. Trouble is, he was a known bullshitter.
He did take part in the Oklahoma Land Rush. That is documented.
Genetic testing shows no Irish, but English, and German.
Oh, also, after them, Negro and Cherokee in me. 22%. (That does perfectly match up with family lore.)
Years ago, I saw that performance in Ireland. The stage was in some restaurant, my chicken dinner was...not up to speed. I had dessert, and beer, and was thrilled, because I was NOT in Texas. And I was learning something.
