Looking for relatives of Larocca grandfather from Anzi

Subject:   Looking for relatives of Larocca grandfather from Anzi

Hi,
I am trying to find living relatives (if there are any) of my late grandfather.
My grandfather Nicola Larocca left Anzi, Potenza, Basilicata in 1904, to come to America. I know his mother died shortly after the war, her name was Angela Sateri, his father was Michangelo Larocca. I know he had some nieces and nephews I remember him writing to one named Michael Larocca up until he died. I'm trying to get some information on his family such as how many brothers and sisters he had, when my great grandparents died etc. Trying to gather some family history. Thanking you for any help
