Adrienne... Did you Antone Sylva have anything to do with dairy farming? Up here in the Sierra Nevada Mountains, there is a Sylva's Dairy and the owners come from a long line of dairy farmers. I know the owner & his family and would be happy to inquire if you think there might be a connection. I understand that there was a Sylva's Dairy Farm somewhere on the San Francisco Peninsula at one time but I am uncertain as to where it was located. Linda
