Mafia Genealogy is a historical research and storytelling website exploring the people, families, and organizations connected to the American Mafia. Its articles trace criminal networks across cities and regions, including Boston, Chicago, Detroit, Kansas City, New Orleans, New York, and San Francisco, as well as Corleone, Sicily. Drawing on historical accounts and biographical details, the site examines subjects such as early Mafia figures, Prohibition-era bootlegging, organized crime investigations, and the influence of gangsters on local communities.

Its coverage also considers lesser-known individuals and family histories, placing them within broader events and criminal enterprises. Alongside its articles, Mafia Genealogy features books by its creator, including In Our Blood and Pasqualina, and shares information about author appearances and book events. Readers can explore the site by location or topic, follow its updates through Facebook, Patreon, and YouTube, or subscribe to receive new posts.
