This is a very strange name, and it makes me think of all the controversies surrounding Pope Pius XII and the Holocaust. I personally think the pope did help the Jews and refused to give in to Hitler, but that's a whole other topic.
Pope Pius XII - during the German occupation of Rome he organised that Italian Jews would be concealed in convents and monasteries. Up to 1,000 Jews were even concealed at the Pope's Summer Residence Castel Gandolfo.
