Pacelli is Pius XII's family name.
But you knew that ! ;-)
Just out of curiosity, I'm going to go and see who it is that identified that individual as then-Cardinal Pacelli, because it is pretty well known that the two men never met face to face.
. . . hmmm . . . searching "Pius XII and Hitler" turns up (1) site that appears to be a Hindu/ Krishna organization of some kind, but written in Polish (I think). (2) Two posts on a photo-posting website in Germany by somebody called "Haakon". (3) Rapture/prophecy site.
OK, I'm completely convinced! :-p
Entering ‘pius xii hitler’ in Google yields a plethora of results. Many more in ‘Images’.
