Have you tried the Family History Center (Mormon Church) Library microfilm? Depending on the Comune they have films beginning in 1809 for Births (NATI), Deaths (MORTE) and Marriages (MATRAMONIO) thru 1910:
familysearch.org/catalog-search
Check their website for the library nearest to your home; you can rent the microfilms and use them in their library to find pertinent records. Some of the records are now online, but the project to convert all their docs to digital format is an ongoing project.
Good luck.
