These are the surnmaes from Tocco Casauria.http://www.italyworldclub.com/genealogy/surnames/abruzzo/pes...
Orlando is not a surname I am familiar with from Tocco Casauria. In fact in Italian the name Orlando is usually a first name and not a surname.
Suggest you do a bit more research, ask more questions of family members. Maybe they can tell you where your Orlando ancestor came from.You might also try to obatain some details from death certificates and Naturalization documents.
I hope this helps a bit.
