Hehehe! I too like to watch celebs and get most correct in matching the old and new pics. Severe traumas do wreck a person's appearance. But, even presidents, prisoners who get locked up as young people, even accident victims, retain a certain ID that, at worst, computer aging techniques could validate. It is not like Anastasia's ID was attempting to match her looks at 11 or 15 to 55 or 60; it was really quite a short time in terms of physical changes.
Nonetheless, poor AA and the real story of who she was is more interesting than her claim. Somehow, she crafted a near-perfect tale of facts and details that set the entire world arguing for 80 years. I think AA was an accomplise to one or more of the executioners, aided the dying Anastasia, downloaded tons of info from the grand duchess, and adopted Anastasia's ID. The real fate, hence, of Anastasia would be the big question in this scenario.
But, back to dear Cecilie....
What did Cecilie do during the second world war? Did she know Count von Stauffenburg and the other royal plotters against Hitler?
