Surviving samples of her tissue yielded DNA that did not match the identified Romanov remains or the remains of living relatives, including Prince Philip. I think they compared her sample with the Romanov remains first, and then with Prince Philip’s DNA profile to make sure.
Thanks! I’m a Romanov/Russian fan as well as intrigued by Rasputin. I actually have a cookbook called “The Rasputin Cookbook” written by his daughter Maria.
