Thanks fou your help.
I had already found this Luiz Furlan's document.
But I need the marriage certificate from his parents .... my great-grandfather.

Hi

I'm looking for the marriage certificate of Costante Furlan e Carolina Manini.

Costante was born at Mareno di Piave in 1859 and Carolina was born at Venezia in 1867

I don't know where and when they married (probably San Vendemiano or Venezia) , but they came to Brazil married in 1895 ...
