Your message interested me. My family background also contains Rizzo on my father"sside. Cologera Rizzo and Baldassare Migliore married and emigrated to US from San Guisseppi Yato, Prov. Palermo Sicily. We are a large family with many relatives still living in S.G. Iato. I have never visited the village in Sicily but intend to do so some day. You peaked my interest in possible family ties.
