Hi Yasmina4,
I am the one that has the posting "Italian Research".
Caivano is a suburb of Naples in the Campania Region.
I could get hold of a copy of the birth certificate for you, but at the moment Italy is in partial "lockdown". The whole of Campania is in the "Red Zone". Meaning no one goes in or out of the Region. Supermarkets, chemist, barbers, hairdressers open. Everything else closed except bars/restaurants for take away only. Curfew at 9 in the evening until 6 in the morning. Public offices are at a standstill and only working for emergency documents.
Make a note in your diary of me and when it all calms down we'll start.
