I actually know something about this because I love English literature. So I am a reader of Caroline Blackwood, and a reader of Nancy Mitford. Nancy's sister--the very beautiful Diana married Brian Guinness. She is grandmother of Tom, Rachel's husband. Diane was not married for long to Brian because she fell in love with Mosley--the leader of the blackshirts in England. They were both arrested during the war for his support of fascism. Also found this little Vogue article on Rachel and Tom's wedding: https://www.vogue.com/slideshow/rachel-chandler-guinness-wedding-photos This is a creepy wedding, replete with an Easter bunny. Hmm. Where have we seen that White Rabbit before.....
