FYI- The Rochester Family, in particular, Stan and Frank Valenti were both made in Pittsburgh under Frank Amato and then John LaRocca. Antonio Ripepi, a high ranking Capo for many years, also the father in law to Stan Valenti and John Bazzano Jr. Ripepi and LaRocca backed the Valenti brothers and they "did" separate from Buffalo after the fallout of Maggadino.

And YES, there was a small crew/family in Des Moines, Iowa run by Louis Fratto, who was under the supervision of the Chicago Outfit. Dallas was run by Joe Civello and was one of the 26 original mafia families.
