Dear Graziella, I'm from Brazil, too. I've been looking for information too, but it's been dificult.My grandfather was born in Poços de Caldas-MG, his name's João Passoni married with Josefa Bologna (both died). My father (Benedito Passoni) didn't know his grandparents, and he doesn't even remember their names, too. My grandfather (João) worked in coffee culture in Poços de Caldas until about 1930 (Sorry my english). I would like to get a answer.
