Now here is an interesting bit of work.  Looking closely you will see that there are three or four photos here, roughly cut up and stuck together.  Pretty creative really.  

We know two of the men here.
The man with the moustache is Vincezo Cafarella, father of Francesca and
therefore father-in-law of Carolina Cincotta Cafarella's son Salvatore. 

The man in the military cap is believed to be his brother Giuseppe,

that is to say Francesca's Uncle Joe.
