So the tins may seem a bit strange but I could come up with a good enough title for my below idea.
During the reign of Edward VIII Prime Minister Baldwin presented three options for the dominions and indeed his own parliament of which all agreed upon the third option. What if instead a mutual agreement occurs around option2 of which was "Edward and Mrs. Simpson marry, but she not become queen, instead receiving some courtesy title." In affect a Morganatic Marriage.
What would happen to history with King Edward VIII and the Princess of Windsor marrying?
