Personal research: I am researching the Palmisano line from Castel di Tusa (originally from Termini Imerese), and the Torretta line from Prizzi. My grandparents met and married in Milwaukee, where my mother and I were born.
I have slides and photos from these Sicilian towns in the 1980s. The LDS Family History Library has since microfilmed original documents from these areas.
I will be posting articles about tracing Italians in both the US and in Italy.
