It looks like Raimondo's wife is maybe Giulia D'Angelo? who was born in Penne, Pescara, Italy?
Let's see if we can get the geography clarified. Raimondo, his sister, his father, and his mother lived at Penne and at Collecorino. These small towns are about two miles apart. They are 7-9 miles west of the town of Pescara, on the east coast of the central part of Italy. Is that right?
So that's the Pescara province, the place name probably needed to find records: Collecorino, Pescara, Italy Penne, Pescara, Italy
Pescara is within the Abruzzi region.
I have an Italian search ahead of me, so thought I'd start by trying to figure out the geography!
