Caleb,
once again you just dont do your research. It has been explained over and over that there is a very good chance that the finger came from Sister Varvara, Ella's companion, who's body was in the mine with hers. They were both dressed identically and it could have been a simple switch of identification. Second, there is no stable chain of possession of the finger, which was kept in a small box and trotted out hundreds of times and handled by hundreds of strangers.
Really, your genuine lack of understanding HOW dna testing works and the science underneath it is appalling...
