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