As a nation state, Italy has emerged only in 1871. Until then the country was politically divided into a large number of independant cities, provinces and islands. The currently available evidences point out to a dominant Etruscan, Greek and Roman cultural influence on today's Italians.
Thank you for responding "Johnnyonthespot". I think that I answered my own question. Bellina-Terra appears to be a variation of the older surname La Terra-Bellina. Based on the information that I have found.
