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