Is it possible that the Giacomo you speak of could have been my Giacomo's Grandfather or uncle???My Giacomo's grandfather was named Giacomo and according to Italian naming traditions he should have named one of his sons after himself and that another son would have named their child after him. If you are related to Sineni's there has to be a link because Giorgia's maiden name was Sineni. Tell me more of the names you are looking for- I have a Gedcom of the Caccamo families Database and lots of documents from my Sineni relatives.
