Hi Rebecca
I just found your old posting and I might be able to connect to your Procaccio/Mola family.
I have a marriage in my spreadsheet of Pietro Procaccio and Rosa Paola Mola, married Dec 14 1876. This makes sense that Michele would be the youngest in 1900.
I will check the parents and see who connects to my files. I have Triggiano ancestry going back to the late 1600s and I am tracing the descendants down so I connect to nearly every family in town. I don't have many Mola but I have enough Procaccio that there is a good shot at a connection.
Let me know anything else I need to know about Michele Procaccio and I'll check on Pietro and Rosa Paola.
