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