The Paginebianche.it (Italian White Pages)can be very useful if you are trying to locate living relatives in Italy or just interested in finding how people people with your surname still reside there.
In the tab which says chi / cosa you type in a surname or you can type a surname plus a first plus an address if you have one. You can also put in the tab that says dove the location in Italy you are searching.
Normally I would just enter a surname and see what comes up. My surname pulled up the names of 111 persons still living in Italy. The majority are living in the province of Reggio Calabria, which is where my ancestors were from originally *but* I have noticed an increase in the number of people living in the North now compared to when I first checked a few years ago.
There are some other very cool features on this site like the curiosità tab which allows you to search the significance and origins of a surname. Give it a try and let me know what you think.
