Historical Romance based in London, a woman turns out to be a the lady whose parents were killed in the Paris riots.


I am looking for a romance novel I read about 5 years ago. The heroine of the book is a woman who comes to London (I think from America) and finds out that she is the daughter of a lord and lady who were killed during the French revolution. The whole family was taught to have been killed during the mobs in the Paris riots. She also has a brother and maybe a sister who survived, but they were separated. I believe her brothers name was John. An older lady she meets (who turns out to be her grandmother) says her looks just like her dead son's wife. That is how they find out she is their daughter.
