Is there a Giuseppe, Domenico, or Rosa in your family ancestry?

The final two records on the next page (Giuseppe, prisonor of war records) are available in digital copy by clicking the "View digital copy" links.
For the other records, you click the Control Symbol link and then follow the directions to request copies.
Hope this helps!
PS: The two prisioner of war records for Giuseppe show his birthplace as Terlizzi, his wife's name Maria, and father's names Damiano, mother's maiden name M. Sabatina Camillo
