Hi, Piero! My name is Diego Graglia and I'm from Argentina. My grandfather's grandfather came here from Italy, and I think he was from Piemonte. His name, we suppose, was Marco, and he arrived in Argentina around 1880. I'm glad to see there is even a little village that carries our surname. I hope to visit it someday. Hugs and kisses to all Graglias around the world, from Argentina!
