It's helpful to have a date range as a jumping off point. Another user shared this useful link with me. It contains photographs of actual records from comunes in L'Aquila and is fascinating to peruse. It's in Italian but fairly easy to grasp. I was told, "Google Translate is your friend." Good advice if you don't read Italian.http://www.antenati.san.beniculturali.it/il-portale
I'm searching in Castel di Sangro (also in L'Aquila), and those records only go up to 1865. It may be different, though, for your comune. Hope this helps.
