FOTR says detailed facial reconstructions on regarding these remains.
Let's see what we have, what solutions I found on one web:
If Marie is No. 5 and Tatiana is No. 6 ~ then the height for No. 6 is wrong.
If Tatiana is No. 5 and Maria is No. 6 ~ then the height for No. 6 is wrong.
If Tatiana is No. 5 and Anastasia is No. 6 ~ then the height for No. 6 is wrong.
If Anastasia is No. 5 and Tatiana is No. 6 ~ then both heights are wrong.
Is Maria is No. 5 and Anastasia is No. 6 ~ then the height for No. 6 is wrong.
If Anastasia is No. 5 and Maria is No. 6 ~ then both heights are wrong.
Solutions number 4 and 6 are not valid. (Then 'both heights are wrong'). It means, at least that Anastasia can't be No.5. We can see that height of body No.6 makes problem, it is leading us to think that those two heights are just similar, just to be Maria's and Tatiana's.
It is too obvious that Tatiana is among remains, both exhumation teams labeled her to be among them. If we choose that she is No.5, than Anastasia must be No.6. However, if she is No.6, than she can't be No5, but Maria. This is just matter of your personal willing to believe in. I would like to hear from your about what do you think which body remains to Grand Duchess Tatiana and why? Then we can , if you wish, discuss more.
Compare:

June of 1917, taken by P. Gilliard, as same as all 'shaved photos'.
About 2007 remains, Russians didn't allow any taking photos of those remains, although nothing much left, only 44 fragments. Remains of the girl are to be 17 - 19. Another source says that she was around 18. Too young to be Maria, on the one hand. I can't find the right information regarding the height of this body.

Not yet. Also, I'd like to know some detailed tests and examinations about 1991 remains, in Russian, available in book' Taina Tsarskih Ostankov'. (The Mystery of Tsarist Remains).
------------------------------
Well, doing this, I felt really odd, since I felt as if I am touching those remains and examining with them. To me, they are holy, they were canonized, and I don't have rights to 'put my nose there I don't have rights to'. However, whether Maria or Anastasia WAS the missing one, now they are finally together.And that is the main point, and not 'which' one is missing. Yet we haven't seen funeral, unfortunately. .
