Hello,
since you already know the name of father of each ancestor of you, I guess you already have copy of their birth record from mormon church!

or already contacted Frosinone civil record office (Ufficio di Stato civile) for copy or certificate of birth, marriage and death record.
Comune
Ufficio dello Stato Civile
Piazza VI Dicembre
CAP 03100
Frosinone- Italy
On the original civil record, there is also written where birth and death occurred, and in what church marriage was celebrated.
If you contact Archivio di Stato di Frosinone,
http://wwwdb.archivi.beniculturali.it/S ... OSINONE%22
you surely find military draft cards and military records; also land records, census, notaries (if they bought or sold any property)
Be specific in your request when you contact the archives or civil record office as above
I hope it helps, bye Riccardo
