Hi Gary, I'm also in Westchester Co. (New Rochelle) and I'm very interested in what your father could tell you. My Grandfather was George Cacase and his father before him was Ercole Cacace, who ended up in Brooklyn, NY. In the 1909 directory for Brooklyn, it shows 3 Cacace's: Frank, Ercole, Louis. Have you heard any of these names? My Grandfather had a brother named Tavi (Octavio) and two sisters, Celeste and Meta.
I'd love to hear from you!
