I have a grandmother named Mary Garofalo who married a Casey Stagno. She died in 1980. She has/had relatives in New York whom we visited in 1958 I believe they lived in the Bronx but not really sure.
When she arrived in CA I don't know. Believe she married young about 1911 at age 16 but not sure. Her parents probably brought her out to CA from NY but not sure. If her father was Girolamo and Maria it may be your connection.
