What if the Mafia isn’t what it seems?
The Mafia is so commonly referred to with the terminology of business or the military that we take it for granted. What if the structure of the Mafia goes deeper, to the family?
IN OUR BLOOD: The Mafia Families of Corleone proceeds from the hypothesis that the Mafia’s original form is the traditional Sicilian extended family. Using original sources — baptisms, police blotters, census and migration records — and an encyclopedic knowledge of the families of Corleone, this book proposes new answers to the biggest questions in the field of Mafia studies, challenging its history, organization, and methods as they’ve been understood by criminologists and law enforcement.
Available on Amazon in e-book, paperback, and hardcover editions. Representing years of research into the families of mafiosi and migrants from the city of Corleone, IN OUR BLOOD is Justin Cascio’s first book.

Hi Justin,
Family stories have been told to me indicating my father was a cousin of Chicken man Testa from Philadelphia. I’ve researched genealogy records and get no where real fast. I can find parents, grand parents and great parents but no cousins or anything else. Wondering if you have advice on how I can find, or not find, the connection that in my gut I know exists. Any thoughts on a direction for me to take? I also know that my grandparents are buried in the same Calvary cemetery as Philip Testa in Delaware County, PA. Other than that, every where I turn I come to a literal dead end.

Have you worked on Philip Testa’s family tree, too? If you’re cousins of any kind you’ll find a common ancestor just by working straight back through yours and Philip Testa’s direct ancestors until you come to a match.
