France

good evening
the best manner is to ask from the Mairie de Chazay d'Azergues (town hall), for the death certificate, by writing all what you know and that your are a direct descendant. (= you are entitled to require a private document)
see the town official website
http://www.chazaydazergues.fr/vie-municipale
If you don't know french, you can use Google translate and making short sentences
