My great-grandfather immigrated to PA from Wales, on my Father's side. I know little about him, only that he was a coal miner and smoked a pipe.
My mother was a refugee from Hungary in WWII, fleeing when she was 18. Her family fled Hungary twice (Nazi's and then the Communists), into Austria, where she met my father. She still has some relatives in Hungary, but never returned to her home country until she turned 75. While my father was in the Army, it wasn't advisable for her to travel in a Communist controlled country.
