So the fact that his father worked for DuPont (and might be spoopy) has no relevance to his last name. His great-great-grandfather came to America 100 years before Paperclip, and that has no relevance to this Nazi named Muller, unless you can find it out.
Basically, you can't say Ahah! This person has the same last name as that person, therefore they are connected!
