Indeed, we cannot refer to it. This should be stated in some thread somewhere. I agree, it is hard to know which body survived- that of Marie or Anastasia. They were close in age, but Anastasia was always much shorter than Marie, I think. This seems to be a factor. We, don't, of course know how much Anastasia might have grown before her death that we don't have record of. But it seems to me that Marie was not the one missing. But the whole thing is difficult, and I just believe what I believe, from what I have read.
