ah... I´ve forgot to tell that Casimiro and Domingos were both sons of Gilberto Fiorentino and Clementina Cippola.
So, the family tree line is:
Gilberto Fiorentino (I don´t have any information about him)
Casimiro Fiorentino (b. 1864, Casoli - Italy)
Tarquinio Fiorentino (b. 1895, Serra-Negra - Brasile)
Enzo Fiorentino (b. 1923, Serra-Negra - Brasile)
Vladimir Fiorentino (b. 1946, Limeira - Brasile)
Renzo Fiorentino (b. 1982, Campinas - Brasile)
Grazie,
Renzo.
