History

Little is known of Mario Castiglione's background other than that he served as a U.S. Marine during World War II, fighting in the Battle of Iwo Jima. He would later support his wife and son by working as a construction worker at the Brooklyn Navy Yard.[2] Mario and his wife legally changed their surname from Castiglione to Castle when their son was six years old,[1] though Frank continued to use his family's original surname up until Siancong War.[4]
