I wish I could point you to an index but I have not found one myself. I've been doing research on Frank Freitas Marianno and his brother Antone Marianno who immigrated from Flores (Fajanzinha) around 1885 and 1881 respectively through New Bedford, MA. They settled in California shortly after their arrival. Unfortunately, I'm scrolling through the same set of parish records trying to locate their parents. Maybe you have some suggestions?
