I was able to obtain a copy of a book on the history of Serradifalco, the home town in Sicily of my great-grandparents, and now the home town of me and my boys. The book is currently out of print and I could not obtain it from any booksellers in the US or Italy. I even asked people in Serradifalco if they could locate a copy, and they could not. If someone else from Serradifalco would like a copy, click here for the PDF files.
There is also a partial translation available from Angelo Coniglio's web site: http://www.conigliofamily.com/SerradifalcoGiuseppeTesta.htm
