Her Majesty realised the fact that she is descendant of Tsar Alexey when she was on a trip from Italy and Austria and she met up with President Putin who had come to visit her in the train. Later her family claimed this and she was handed a book about the iranian sovereign man who hosted the Tsar Alexey and Tsarina Anastasia, with the fact that she has shared the photo of Tsar Alexey on Internet platforms like Flickr like Pinterest and instagram and reverbnation.com. Her grand mother has acknowledged that her husband was absolutely Romanov. And that some of the evidence based on her family cannot be unleashed now.
