Emigration ports

[joshuaross]

Where could I find passenger lists for emigrates from Italy? I am looking for family that left in 1898 and went to Brazil. My great-grandfather went there with his parents and siblings. I do have his Ellis Island record from 1906 that states he emigrated from Naples. So, logic says he went to Brazil, back to Italy, the to the US. I know his two brothers lived in Brazil in 1947 because I have a letter from one of them. Did Italy keep records of people leaving/coming? Thanks.
