My husband's family is Guerriero from Detroit. I have been researching the family trying to put together a genealogy report.
His Grandfather Aniello Guerriero, was born 1884 in Avellino. He had a brother named Pellegrino. Aniello married Maria Grazia Masucci before coming to the US in 1909. Their children were Anthony, Clara, Nellie, Frank, Angelo and Maria. Anthony was my husband's father.
Always happy to compare notes.
