Concerning Vincenzo Crusco, I think we have a common ancestor. My Great Grandfather Felice Cipolla (AKA Felix Cipollo) arrived on the Alesia from Naples on May 19, 1893 from Muro Lucano. He was age 15. Who did Felix come with? He came with his sister Rosemarie or "Rosa." The ship manifest lists Rosa Moglie (age 19) just before Felice on the manifest. Moglie is Italian for "wife" indicating that the person listed above Rosa, Vincenzo Crusco (age 21) in the list is Rosa's husband. Rosa was 19.
Vincenzo and Rosa are buried in Holy Cross Cemetery in Yeadon, PA (Philly suburb). He died in 1960. She died in 1957.
I have several documents and pictures that might be of interest to you.
1. Ship manifests
2. Census documents (1910 & 1920)
3. A photo of Vincenzo & Rosa

I'm very curious about the success you had searching for Vincenzo's family in Muro Lucano. I'm eager to find a way to find search for roots in Muro Lucano.
