Based on the information I personally believe she was, there are to many facts that are parallel.
She claimed to be Anastasia and was one of the best known of several imposters. However it was realized that the real Anastasia was killed with her parents and silblings during the revolution. They found the body of the real Grand Duchess Anastasia in 2008.So no, she was not.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
