His brother Stanley was made at the age of 28 which would make the year 1954 into Buffalo family. Stanley sponsor was Giuseppe Ida. Frank reached out to his brother to be transferred. Sometime in 1955 Stanley met Joe Bonanno and a friendship began between the brothers and Joe Bonanno. 1960 and on, Stanley and current Rochester capo Jake Russo did not get along. Frank comes back onto the scene and in 1964 Jake Russo disappeared. Frank killed Russolesi and paid tribute to Stefano Magaddino until the late 1960s. Magaddino felt his cousin Bonanno was involved.
