Biography

DeSimone was born in Salaparuta, Sicily, in Italy, on December 11, 1873. He initially settled in New Orleans before moving to Pueblo, Colorado. In Pueblo he was part of that city's Mafia organization, and was evidently well-respected. He became a close ally of Vito Di Giorgio in Los Angeles. Upon Di Giorgio's death in Chicago in 1922, DeSimone took power. His empire spanned over Los Angeles County. His rule in Los Angeles was brief, and he stepped down around 1925. He later became a legitimate businessman who settled in Downey, California. Rosario died of natural causes in 1946.

Family

DeSimone married and fathered several children. His son by his first wife, Leon DeSimone, graduated from Stanford University and became a successful Los Angeles surgeon. DeSimone fathered two sons by his second wife Rosalia Cordo. Frank DeSimone, his second son, became a criminal attorney and later don of the crime family, reigning from 1956 to 1967. His third son, Joseph, became a dentist. His first and third sons had no interest in leading a life of crime. DeSimone also had two daughters, Josephine and Towina.

Several of Rosario's other descendants also became involved in the Mafia. They include his grandsons Thomas DeSimone, Robert DeSimone, Anthony DeSimone, and Joseph DeSimone. Others include his granddaughter Dolores DeSimone and relatives Franky DeSimone, Ralph DeSimone, Phil DeSimone, and James DeSimone.
