I have a friend that wanted me to post this question here for them. They are wondering, exactly what region or regions the surname Colletti are from in Italy? They have a grandmother with the surname, he told me that they are from Naples but moved to Sicily or might of stopped in Sicily before immigrating to the United States. They are wondering if this name is typically found in Southern Italy or is it common in the North also? If anyone can give me some background on the surname, common areas its found in or anything else general about the name so I can pass it on to him, he'd appreciate hearing it. Thanks.
