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