We suppose that Prince Edward has never meet Mrs Simpson.
Edward ascends the throne as Edward VIII,and despite he is personally not hostile to Hitler and favorable to appeasement he
fulfills his duty through and through.
Came the WW-II and he is a popular and brave King.
Edward VIII not ever get married (he have several discrete lovers),so the heir to throne is Princess Elizabeth,daughter of his brother the Duke of York.
At last Elizabeth become Queen in 1972,after the death of his uncle.
The question is,can in this timeline Elizabeth married
Philip of edinburgh?
And if yes,can his first male son (Charles or a alternate Charles) become king in 1972 bypassing the mother?
