The maternal relationship between Anna Catharina Stammen and her daughter Maria Gertrud Bellen is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MGC.

The segmental (via DNA segment triangulation) and total DNA shared between MGC and other confirmed descendants of Johann Peter Martin Stammen/Magdalena Remmers is consistent with the expected ranges for their respective relationships. Since MGC descends from Johann Peter Martin Stammen/Magdalena Remmers through Anna Catharina Stammen and her daughter Maria Gertrud Bellen, the presence of significant shared DNA between MGC and other known descendants of Johann Peter Martin Stammen/Magdalena Remmers validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Johann Peter Martin Stammen/Magdalena Remmers through Anna Catharina Stammen to Maria Gertrud Bellen, and ultimately to MGC, confirming this direct ancestral connection through multiple generations.
