Margaretha Martens (21 Dec 1942 - ABT 1970)

The maternal relationship between Margaretha Martens and her daughter ED is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant ED.

The segmental (via DNA segment triangulation) and total DNA shared between ED and other confirmed descendants of JD/Helena Penner is consistent with the expected ranges for their respective relationships. Since ED descends from JD/Helena Penner through Margaretha Martens and her daughter ED, the presence of significant shared DNA between ED and other known descendants of JD/Helena Penner validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple JD/Helena Penner through Margaretha Martens to ED, and ultimately to ED, confirming this direct ancestral connection through multiple generations.
