The maternal relationship between Helena Fehr and her son BGK is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JH.
The segmental (via DNA segment triangulation) and total DNA shared between JH and other confirmed descendants of
Johann Wall/
Krahn is consistent with the expected ranges for their respective relationships. Since JH descends from Johann Wall/Krahn through Helena Fehr and her son BGK, the presence of significant shared DNA between JH and other known descendants of Johann Wall/Krahn validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Johann Wall/Krahn through Helena Fehr to BGK, and ultimately to JH, confirming this direct ancestral connection through multiple generations.
