Families have changed their last names before in response to world events. After Adolf Hitler was defeated, not only did other people named Adolf change their name but members of the Hitler family changed their last names.

It doesn't seem inconceivable that some families had to distance themselves from the oppressors through a last name change to fit in with everyone else. Then some of those may have still felt a bit defient of the new world order and so not followed the tradition in their children's first names.
