Hi, I think this photo was taken around 1870, just after the unification of Italy. It could be later, 1890 maybe. But he's a youngish man there, and he was having children in the 1870-80's. I don't know if he was involved in any battles related to the unification of Italy? I have no idea. He would have been too old for World War One, his son, my great great grandfather fought in that war, in the British Royal Field Artillery. Thanks.
