The photo I have of Sabatino Pagni and his family was taken from someone's tree at Ancestry. Due to the fact I do not know how to properly download photos I am not sure whose tree it came from. I predict yours. I have a photo of a man named Raffaello Stefani and Pamela Gagliani but I think it might be incorrectly labeled. My Raffaello Stefani and Pamela look very much like your Sabatino and his wife just that yours are older looking and a bit smaller weight wise.
Not sure if you can see on my tree but look up Raffaello Stefani and Pamela Gagliani and see if you think they look alike. I am thinking my photo is labeled wrong. I know nothing of Pasquina Pagni just that she married Ezio Vannelli. They were my great grandparents.
