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