The maternal relationship between Doreen Bauman and her daughter CK is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant GW.
The segmental (via DNA segment triangulation) and total DNA shared between GW and other confirmed descendants of
Andreas Ludwig Grünke/
Mathilde Hübner is consistent with the expected ranges for their respective relationships. Since GW descends from Andreas Ludwig Grünke/Mathilde Hübner through Doreen Bauman and her daughter CK, the presence of significant shared DNA between GW and other known descendants of Andreas Ludwig Grünke/Mathilde Hübner validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Andreas Ludwig Grünke/Mathilde Hübner through Doreen Bauman to CK, and ultimately to GW, confirming this direct ancestral connection through multiple generations.
