Rossano - Grande family

I am looking for information about the Rossano and Grande families, possibly related to the Volpe family. My grandparents, Giuseppe Rossano and Rosa Grande married - probably in the late 1800s - and emigrated to New York, where they had four children, including my mother, Maria (Marie). My mother's uncle, Nicola Rossano, also came to New York around the same time with his sister.
