Thanks for your replies and help, some good clues where to start there.

Thanks very much to both of you, unfortunately the Italian Town Finder didn’t recognise “Via Piedilmonteâ€

Hallo, Can anyone help me to locate Via Piedilmonte (esp number 2) on a map? It must be in the area of Atina or Belmonte Castello in Frosinone. My Grand Father‘s family lived there in the middle to late 1800’s.
Thanks for any help.
