I"m not in the mood to get back into this, but I must comment on this part:
2.) Her really amazing knowledge of intimate family details and traits... how did she know this?
Easy. SOMEONE TOLD HER. One thing I never realized in the days of being a semi believer before the DNA tests was that Europe was full of Russian refugees and emigres'. Literally thousands of people made it out of Russia who had known the family or at least the royal court. There were 1600 members of the court who were around the family a lot, add to that their families and friends and the number grows even higher.
Besides the famous ones we hear of, they originally took a rather large entourage into exile in Siberia with them, meaning dozens of people were with them right up until they were sent to Ekaterinburg. Only about 6 of these ended up dead as far as I know, 3 shot with the family, 3 others executed at other times.This leaves still more people who would have known a lot. Think about it, just about every Russian noble who wasn't killled in the revolution, civil war or terror fled the country, most of them to France or Germany. So what I'm saying is, there were PLENTY of people around who would have been able to give her tips, either intentionally or incidently in conversation, about the family and their surroundings.
Personally, my main suspects are Gleb Botkin and his siister Tatiana. Children of the family doctor, they had been in the palace, played wtih the children, and went with them to Tobolsk. Gleb was a very imaginitive person who had created entire animal lands full of named and illlustrated characers when he was just a kid, and was a journalist in NYC at the time he championed AA's cause. He was a writer, this was a good story. He had the memories, she played the part (kind of like Dmitri in the "Anastasia" cartoon?) It makes perfect sense to me. Her claim really didn't take off and gain worldwide acclaim or go to court until after she took up with the Botkins.I'm not sayign they were the first, or the only ones though. I'm saying she could have gotten infor from many people, and the chances were there, since there were so many Russian emigres around.
One more thing to consider is that several people very close to the faimily, like Gilliard, Anna Vyrobova, Lili Dehn and Sophie Buxhoevedon all wrote very detailed books on their years with the royal family, and were published in the early 1920's. There were also other books, articles and pictures she could have seen and read, or been shown or told about.
Another factor in this is that she really didn't know all that much, and what she did say was usually off the mark some.She got the details of a secret room wrong and confused an injury of Marie's with bieng Anastasia's. This tells me she was getting her info from somenoen with intimate yet limited knowledge of the family, like the Botkins, or a courtier, or a servant.
And then there's the issue of who verified these 'things only Anastasia would know?' The entire family was dead, and the closest friend, Anna V., was never consulted. I really think the statement that she knew a lot is very exaggerated and not accurate when you really look at the details. In the end, I donl't think there is anything she said that can't be explained away as having been told to her by someone who was there.
