The maternal relationship between Helena Dueck and her daughter
Margaretha Martens 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
Johann Dyck/
Helena Penner is consistent with the expected ranges for their respective relationships. Since ED descends from Johann Dyck/Helena Penner through Helena Dueck and her daughter Margaretha Martens, the presence of significant shared DNA between ED and other known descendants of Johann Dyck/Helena Penner validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Johann Dyck/Helena Penner through Helena Dueck to Margaretha Martens, and ultimately to ED, confirming this direct ancestral connection through multiple generations.
