Oh, dear! This will be a very sad time for the Queen. Was Margaret the last of Elizabeth's contemporary women friends? I remember my mother losing the last of her contemporaries. There was no-one left with whom she could discuss the old days and remember her as a young woman. At least Elizabeth still has Philip.
The two Mountbatten ladies are still alive I think , she would have been friendly with them all of her life as well been cousins to her and to Philip . Also she has her Kent cousin Edward & Alexandra who she is close too. Don't know if Margaret was the last of her generation from the Bowes Lyons .
