Jermaine, if you're going to bring up languages, you must also consider the language evidence AGAINST her. There is really no documented proof she spoke or was even competant in Russian, did anyone ever give her a school type test? Even during the lenghty trial? She knew absolutely no French, and her English was atrocious. She seemed to have learned all these bits and pieces of languages as her claim accelerated, probably with the help of supporters a la 'My Fair Lady.' German seemed to be her most fluent language. We also don't know if all of those reports from individuals- which is really all we have- are truthful or accurate. If you believe them all, and you're making a list, you should also consider Felix Yussopov saying he spoke to her in English, Russian, French and German and she only responded to the German, and the people who swore they heard her yell out in Polish in a church in Virginia in her old age. There's just way too much he said she said for me for the language thing to hold much water either way.
If we were using languages to contradict her being AN, I could post a lot more.
I have question for you though, if you don't think she was FS, why did her DNA match FS's nephew with 99.9% certainty? Why did FS vanish, never to be found again, in the same time and place as AA appeared? How can you explain how she closely resembles the picture of FS? Don't you think there's quite a bit of evidence she was FS, and nothing to really discount it?
