Revis, Apulia is the english name of the region,in italian is Puglia,Dwalin in the American Mafia with a few exceptions, the second or third generations of Italian-Americans don't speak Italian, they know only the minimum Cosa Nostra, omertà, caporegime etc.
It's happened to the sons of my uncle that emigrated to Canada, they speak English and only my uncle and aunt speak italian with us.
