My aunt didn't really know them. My great grandmother and my aunt took a trip to Italy after my great grandfather died. My great grandmother wanted to meet her husband's family. It was 30 or more years ago so the things she tells me now are only on her memory. I only talk to my aunt on the phone and she talks fast - and she repeats the word "he" so much i sometimes get lost whether she's talking about an uncle, father or son, but she has told me that Marciano had sons and nephews named Marciano. But I'm sorry, I don't know any details of when they were born. And I don't know for certain the names of the people in the photo.
Were you able to show your grandfather the photo?
