Charles Francis Greville

So who was The Right Honorable Charles Francis Greville? He was the second son of the Earl of Warwick,  once occupied a seat in Parliament, was brother to the King's equerry, was a member of several scientific societies, and owner of one of the most extensive mineral collections in the world which would become the basis of the collection in the British Museum. Lord Greville did have that vanilla orchid bloom in his greenhouse, but he is probably better known for having Emma Hart in his bed. He took her in pregnant by another man, moved her to his previous dwelling on Paddington while he lived part time elsewhere, changed her name, and began to instruct her in everything it would take to introduce her to finer society. She was a beauty and painted by George Romney in several different costumes. Romney also did this portrait of Greville. Here it is. Check his features out because I am going to have some questions about him. Yeah, and so what became of this Emma Hart? Why don't I know who you are talking about, yet?
