My step-father is a Castagna and he was born over there in Italy . His father was Dominick Castagna they came from Capastrano near Pescaro. His father came to America first than later on sent for his family. My step dad live in Florida now and is 80 next year he is a violinist/teacher. He came to America when he was 12. They all settled on Long Island. I will send him your email see if the name rings a bell for him. He and my mom visited the area in the early 1990's. Maybe this can help.
