It's certainly been a while, but I thought it was finally time to provide a recent update. Great (yet sad) news! I have finally found out what happened to Maria Bini, sister of my great grandfather Cosmo. A month or two ago Ancestry.com added death records for Pennsylvania. I knew Maria's husband Antonio Palmisano was living in PA when they got married, but for some reason I never thought to look for Maria there. My uncle's story of them living in Endicott, NY had me spending hours calling churches and cemeteries in the area, but to no avail. So when I saw the new PA records available, I decided to try a search for the heck of it.
Lo and behold, there she was! She died June 7, 1922 from eclampsia at 8 months pregnant. Unfortunately, the child was stillborn. So Uncle Phil was (mostly) right after all.
While I'm glad the mystery has finally been solved, I was hoping for a happier ending, perhaps long-lost cousins living in Endicott or even PA. But there are still the mysteries of Cosmo's elusive brothers Guiseppe and Francesco, yet to be found in Italy, Brazil, or Argentina.
The story's not over yet!
