To do a search for every cemetery in a particular region in Italy, begin with a full search for all of Italy.
Now go into the address bar at the top of the screen, where the url reads the following:http://www.findagrave.com/cgi-bin/fg.cgi?page=csr&CScn=&CScntry=9&CSst=0
In the last segment of the string, replace the 0 part of the CSst=0, with any one of the following codes, which will then drill the search down to the chosen region level.
1928 Friuli-Venezia Giulia
1939 Trentino-Alto Adige
1941 Valle d'Aosta
