Hello Tom....my grandfather was Francesco Cipparrone of Pietrafitta, the older brother of Giovanni and your father-in-law's uncle. I am guessing that Jack's mother was Antoinetta Lopes, whom Giovanni married in Italy in 1912 before returning to San Francisco, where his brother Antonio lived. Like Francesco they were barbers! My grandfather died in 1927 at age 44.
You post was the first I'd heard of Giovanni and Antoinetta having progeny. If Jack is still with us please tell him he has a 92 year old cousin named John, the only one of Francesco's surviving sons, in New Jersey. If you and/or he would like information regarding Francesco's other children please post.
