Your great grandfather Francesco(Frank) was the third child of Nunzio Corso and Antoinetta Lo Picolo of Palermo,Sicily.His siblings were: Moma, Maria, Marianna, Giovanna, Gaetana and Antonino(my father). Francesco,Maria, Marianna and Antonino immigrated to the USA.All to Homestead, PA.Your great grandfathe married Josephine Franzetta before coming to America.Maria and after her death,Marianna married Francesco Franzetta,Josephine's older brother. My father,Antonino was the youngest of the family.He marriedTheresa Abramonte,the daughter of Rosalia Franzetta Abramonte who was the oldest sister of Josephine and Francesco Franzetta.You can see that the Corso Franzetta connection is very strong.None of the other Corso sisters ever came to he US.None areliving,however, there are two daughters of Giovanna and one daughter of Gaetana living in Palermo. My family lived in San Diego in the late forties.I remember your grandparents as a young married couple.I remember when your mother and your uncle Francis were babies. I'm glad to have made contact with you.I hope that I have been of some help to you.
