My great-grandfather, Giuseppe (Joseph) Alfonso was born in Morrone del Sannio in 1888 or 1889. He came to the U.S.around 1906. He married Leonora Stanziano, who I believe hails from Castellino del Biferno, although I am not exactly sure. His father was Luigi Alfonso and his mother was Maria Stella Carbone.
Do any of these names sound familiar to you? I am working on a family tree and planning a visit to Italy soon.
