no, they met in 1939 and she fell in love with him than and they wrote back and forth through the war, I don't know the Queen so I can't say if she's the type who wishes to be alone in times of pain or reaches out and pulls loved ones in, but I think this would make them closer not end their relationship, likely they'd be married ether when she turns 18 or the war ends, which ever comes first
That's one of those urban myths that have never actually been evidenced.
Princess Elizabeth was 13 when she met Prince Philip in 1939.
In a scenario where Elizabeth's father and mother have been murdered, things are going to be different. Elizabeth and Margaret are likely going to be raised by Queen Mary, probably even more conservatively and secluded than they actually were!
Mixing with the young Queen is going to be near impossible and those allowed near her will be vetted closely by Queen Mary.
Queen Mary loathed Lord Mounbatten and was responsible in 1952 for a serious conflict in the Queen and Prince Philip's marriage by insisting to Churchill that the royal house should remain Windsor and not be renamed Mountbatten, which Philip and his uncle expected. Queen Mary is likely to try and prevent any interaction between her grandaughter and the Mountbatten family i.e. in October 1946 Princess Elizabeth attended the wedding of Mountbatten's daughter Patricia where she was seen with Prince Philip. Its unlikely the young Queen Elizabeth II is going to be socialising as she was in fact able to do as Princess Elizabeth.
Philip's ancestry is going to be even MORE controversial in a situation where the young Queen's mother and father were assassinated by Nazis.
Remember in 1947 none of Philip's surviving sisters were invited to the wedding because they were German, two of his brothers-in-law had fought in the Nazi German army. That is why Philip had to distance himself from his German heritage and become Philip Mountbatten....imagine how much more controversial it would be if Elizabeth's parents had been murdered by the German airforce!
Queen Mary is key here! Remember she and her husband George V had deliberately rebranded the monarchy to emphasise its Britishness to protect the image of the monarchy. They had changed the family name to Windsor and even broke centuries of German royal tradition by allowing their children to marry into the British aristocracy rather than marrying minor German princelings.
Is she going to favour her grandaughter making such a match?
