Looking for Vivoli relatives in Missanello

I am looking for relative of my grandnother, Grazia Vivoli. She came to New York with her father, Rocco, in 1911. My grandmother, Grazia Vivoli married Peter Russo in New York in 1913. It is said that my grandmother left behind in Italy a sister, Carmen, and a brother. Relatives of her siblings is what I would like to try and get. Any information would be greatly appreciated.

Thanks so much
