Yes I'm still interested in getting info. Frosinone is the name of both the town and the province. My father's family is from the actual town. His name is Antonio. I have gone as far back as my great great grand father whos name was Pietro Angelo Mastronardi. His birthday is only a guess and I would say somewhere in the 1860s. His son, my Great Grand Father, was Giacomo and his son, My Grand Father was Ernesto. Some of Pietro Angelo's sons did move to Australia and his grandchildren and great grand children are still there.
The relatives I do know are my father's first cousin and her family. Her last name is Lina Mastronardi. Her Husbands name is also Mastronardi, first name Guglelmo, but my father says he is not related to us. They are near Canberra and are apple farmers.
I have the names of Pietro Angelo's kids that moved to australia but birth dates are only guesses. Their names were Benedetto, Vincenzo and Domenico. Benedetto and Vincenzo are dead I dont know If Domenico is. I'd be interested to know if any of these names are known to you or your family.
I have also sent you an email with some of this info.
