I seems we are speaking of the same Billy Parisi(married to Rose).
My "uncle" Bill was married to Rose(my mistake), and he was godfather to my twin brothers. He had an older brother, an older sister, and 2 younger brothers (plus other siblings, but these all died as young children).
There's only one problem: You tell me that your grandfather's parents were Biagio and Josephine. These would be my uncle Bill's uncle and aunt, not his parents. Are you sure about your great-grandparents names?
Let me know, O.K? You can email me directly by clicking on my name here on the messageboard.
