From what I understand, Ottovio and Theresa came over from Italy, and had John Mazza. My Grandma Margaret and Grandfather John married and had three, Theresa, John, and Otto II. Margaret Feldman Mazza originated over in PA, so I would have to think that our Mazza's lived near there, but it could be NY, NJ..Who knows? I am Otto's son. Any help would be appreciated..Very interested to meet new family!!
