CORSO Gaetano from scicily to morocco..

Hi everyone,
I am trying to found informations on my family.
My grand father, Gaetano Corso, moved to Morocco from scicily but no records of our family past was kept.
He died in Montpellier France in 1962.
The only feature that I remember form him, is that he was deaf in the left hear after being shot during a war, and that he fought with Garibaldi but no other details or dates as ever been found.
Please if you have any details even remote that can help, e-mail me.
Thanks
