Editing Williamsburg Gang (section)

==Formation and leadership==
The group's social base came from the [[Castellammaresi network (New York City)|Castellammaresi migration and kinship network]]. Shared birthplace, marriage and neighborhood ties concentrated interrelated Sicilian immigrants within a few blocks in Williamsburg. The organization was heavily Castellammarese in composition, although Schiro himself was born in Roccamena and raised in Camporeale.<ref name="Critchley">David Critchley, [https://books.google.com/books?id=2eCPAgAAQBAJ&pg=PA214 ''The Origin of Organized Crime in America: The New York City Mafia, 1891–1931''] (New York: Routledge, 2009), pp. 212–230.</ref>

Warner, Santino and Van't Reit cautiously reconstruct Sebastiano DiGaetano as leader around 1909 or 1910. Schiro succeeded him in March 1912.<ref name="Warner" /> This transition is the defensible formation point for the conventionally named [[Schiro crime family]]: the same Williamsburg borgata continued under new leadership rather than being created by a later merger of several corporate gangs.
