This is a link to the films available from the Family History Centre (familysearch.org)for one of the areas you mentioned (Mussomeli)
There are 2 other areas mentioned as well relating to Mussomeli with films available for them too.
I couldnt find any films available for Amerina.
You can hire the films from your local Family History Centre you can find the nearest one to where you live if you scroll down to the bottom of the page where it says 'Find a Family History Center then fill in your details
Hope this helps but I'm not sure if this is what you were looking for.
