Maria Harder (18 Jan 1814 - 24 Apr 1885)

The maternal relationship between Maria Harder and her daughter Helena Martens 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 Maria Harder and her daughter Helena Martens, 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 Maria Harder to Helena Martens, and ultimately to DJG, confirming this direct ancestral connection through multiple generations.
