The maternal relationship between Eva Rosina Giese and her son
Christoph Bartig is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant CS2.
The segmental (via DNA segment triangulation) and total DNA shared between CS2 and other confirmed descendants of
Gottfried Giese/
Anna Maria Nast is consistent with the expected ranges for their respective relationships. Since CS2 descends from Gottfried Giese/Anna Maria Nast through Eva Rosina Giese and her son Christoph Bartig, the presence of significant shared DNA between CS2 and other known descendants of Gottfried Giese/Anna Maria Nast validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Gottfried Giese/Anna Maria Nast through Eva Rosina Giese to Christoph Bartig, and ultimately to CS2, confirming this direct ancestral connection through multiple generations.
