CROTTI SURNAME

I have relatives that were
from Italy, but through family stories have been told that after they were
married they went to South America, possibly Brazil. I have looked and
can't find a good place to research the family. I am not at all familiar
with South America. The woman would be my great aunt--named Agata
Manfucci(b. 1879/Italy) and she was married to Giorgio Crotti(b. Genova).
They were married Dec. 1905 in Italy and he was a Sea Captain in the
Military. I am trying to find where they lived in South America, where they
died and if they had children. The Surname would be CROTTI . Any help
would be greatly appreciated.
