Sono francesa, non parlo italiano, capisco un po
Ricerco uno matrimonio in Napoli de :
Vincenzo Chiaesi/chiaese con Maria Pisano/pisani avanti di 1863
Hello
I'm french, I don't speak italien, I just understand it a little.
I am looking for the weddind act of my ancestors who lived in French Algeria.
I found a record of a death certificate of (I guess) their first child who was born in Algeria, January 1863. It says that the parents were married in Naples
see the record here :

She was 21, he was 33 year old.
I don't know how to begin my research.
Thank you very much for helping me if you can
Grazie mille per aiutarme
Hélène
