I wonder under what name they do process any legal documents in the US...I guess all of that is taken care of for them.
But I think Edward VIII and Wallis were still called Duke and Duchess by everyone...
Of course, Edward never expressed a desire to leave the family business, until it was clear that he could not marry Mrs. Simpson. He was pushed out, more or less. And Wallis Simpson was deeply desirous of a title.
The Sussexes seem to be making contradictory statements with their actions. They want to be considered royalty, but don’t want to do the things that royalty must do- like stay out of politics.
