Dear Friends, I am looking for my great-grandfather and great-grandmother - Giacomo de Angelis and Antonia Peruzzini. They emigrated from Italy to Brazil.

I tried the FamilySearch website, but the province of Rome is not cataloged yet.
Already I contacted the Stato Civile di Roma but as my great-grandfather was born in 1861 - 1868 is difficult to find something in the commune and churches.

I know the surname "de Angelis" is common in central Italy, but if they have any experience with these surnames and any tips or any site to indicate, I will be immensely grateful.

Thank you.
Alexandre de Angelis

Perhaps some document, like a marriage, in Brazil has the name of the parish where they were baptized. If you know this, then you can contact the church.
It may also be possible to locate a military record since he would have served around 1871.
