The place must be Valguarnera Caropepe in the province of Enna. I can't think of anything else remotely spelled like that, unless it is very small. That's the 1950s, right? That's Rosa (or Rosaria or Rosalia), Giuseppa (or possibly Giuseppina), Pietro, and Carolina (or perhaps Caterina or Carmela, much more common names). Surname Latina or Latino (much more common in Sicily). How are these people related to each other?
Unfortunately it seems that FamilySearch.org doesn't have records from Enna.
