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