Hi! Welcome to the forum! Calabria is a region that covers the southern portion of Italy (except for the heel of the boot). Calabria covers hundreds of miles and 5 provinces - kind of like our states. The Provinces of Calabria today are Cosenza, Catanzaro, Vibo Valentia, Crotone and Reggio Calabria. Vibo Valentia and Crotone did not exist prior to the 1990's when Catanzaro province was split into 3 provinces. Rocca di Neto is (today) located in Crotone Province. Their website is here: www.roccadineto.net/
You say you have family censuses? Is this where you got the name of the town they came from? Were they all from there? Do you have their ship records? If you really want to find out relatives that may live there today, you need to know who you are looking for in my opinion. It must have been a really small town because there are only 6 microfilms for 100 years worth of birth, marriage and death records for the town in the LDS catalog. You can trace your family back then through those records and make a family tree so you know historically who you were related to then search all the surnames in the Italian phone book here: www.paginebianche.it/index.html
Under "cognome" type surname, under "dove" type the town name.
You can look there now but until you know more about your family, any connections would be questionable.
If you need help finding manifests or anything else, let us know.
