The Bolsheviks Are Righting

Bolsheviks acided the children and buried them in marked graves. They later found some of them, but not all of them. When they were trying to piece together what happened, they hadn't found the place where anastasia was buried. So there's certain stories about impostor anastasias who claim to be anastasia. But once d na evidence becomes a thing,  they prove without a shadow of a doubt that it was the full remains of grand duchess anastasia who was killed.
