Sorry itīs in Italian in parts, but itīs got English subtitles too so that you can follow... The undertitle reads "Sulle trace di Agostino Coppola" = tracking down August Coppola, that is to say, Nicīs great grandfather. He emigrated to the States at the turn of the century from Bernalda, a little town in southern Italy.
I can relate to this story. My own great granparents had to emigrate too, to Cuba and later to Mexico. They left their village behind, but not their roots.
