Thomas,
Very interesting story, to think that there's people out there denying the existence of concentration camps. Was your great grandfather an immigrant himself?
I wonder why the web site says "Polonia in California"? I mean, "Polonia" means "Poland" at least in Spanish and Italian, and I was under the impression since I was 10 years old, that Poland in Polish was "Polska" (explanation: I remember that from reading the back of the sport jackets of Poland Soccer National Team's players in Germany's World cup 1974).
Regards,
