Interesting fact
I watched this movie about 2 months ago and found the story of the Eliza, her mother, the Duchess of Devonshire, and her father, Charles Grey, to be sad, yet fascinating the more I researched the real story. Recently I looked up a bit of interesting genealogy regarding Eliza's half-siblings/relatives on both sides:
Charles Grey's son with Mary Ponsonby, the Rev. Hon. Sir Francis Richard Grey (what a title!) married the daughter of Georgiana Cavendish, who, in turn, was Georgiana, the Duchess of Devonshire's granddaughter. Her name was Lady Elizabeth Howard. A bit confusing, I know.
So this means Eliza Courtney's half-brother Francis on her father's side married her half-niece Elizabeth (Eliza's half-sister Georgiana's daughter) on her mother's side. Wow! Never know with the U.K.'s aristocracy what you will find in their lineages!
