Does anyone know what I can do?

I can't go on with my search because I can't find my great-great-grandfather's marriage and birth certificate.

His name is Camilo Credidio (Italian)

Father: Luigi Credidio (Italian)

Mother: Maria Luigia Credidio (born Fera) 

Spouse: Rosa Credidio (born Papa)  - First spouse

Siblings: Giuseppe Credidio - 1857 - ? / Francesco Battista Credidio - 1861 - ? / Gio Battista Fillipo Costantino Credidio - 1859 - ?

One of his children: Ernesto Credidio

Thank you in advance,

Hello @ElizangelaAlves da Silva.

We are not quite sure what you mean when you say you can't go on with your search?

Are these ancestors in FamilySearch Family Tree? If so, can you provide their ID numbers so we can take a look?

There are various ways to get help with your genealogy. Here is a knowledge article that might help you:

A continent to start with would be good....

Depending on where you believe these births and marriage to have occurred, you can join an appropriate group here in the communities and ask your question in that group. (Amended with as much specifics as you have.)
