Is there something we can do with the following genetic information?

Question

In researching Adelheid von Alpeck (d. 1280) I came across the following forum entry for Eupedia.com:Haplogroups of European kings and queens:

- Tzar Nicholas II of Russia (mtDNA haplogroup T2 : 16126C, 16169Y*, 16294T, 16296T, 73G, 263G, 315.1C)
* heteroplasmy for 16169Y (common within haplogroup T).

All the members of haplogroup T2 above descend from Adelheid von Alpeck (died 1280), daughter of Witegow von Alpeck.

Their most recent common matrilineal ancestor is Elisabeth of Bohemia (1409–1442), daughter of Sigismund of Luxembourg, Holy Roman Emperor, and Barbara of Celje.

Is this useful information in any way and if so how can it be used in WikiTree?

Answer 1

On WikiTree we currently have Nicholas II's maternal line ancestry back to Kathryn von Pfannberg but her profile is unsourced as are several descendants.

I think I've seen something that states that Barbara von Cilli is the maternal line ancestor for which every generation from her to Nicholas II is definitely confirmed.  Any maternal line ancestors of Barbara von Cilli are possibly unsure or disputed?

I'm not sure where Eupedia gets the information to take the line back to Adelheid von Alpeck?  Whether it comes from reliable sources or just what might have been found online?

Answer 2

I find it too general to be very revealing. I hope someone can prove it otherwise.
