I had a great uncle who left Italy with his family and went to Argentina. He was Romulo Vacaiani (sometimes spelled (Vaccaiani) who married Josefa (Josephine)Petronari. He was born in 1900 and I assume he went there in the 1920's. I actually found a query placed in an Italian gen forum by a grandson, Cristian Arana from Argentinain 2002. I have tried to trace the email address back but it bounces back as a time out so I do not know if it is valid or not. I have no idea of where in Argentina they lived but I think it may be near Buenos Aires. Any Suggestions ?
