The maternal relationship between Maria Giese and her daughter
Anna Gartzke is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JR.
The segmental (via DNA segment triangulation) and total DNA shared between JR and other confirmed descendants of
Gottfried Giese/
Anna Maria Nast is consistent with the expected ranges for their respective relationships. Since JR descends from Gottfried Giese/Anna Maria Nast through Maria Giese and her daughter Anna Gartzke, the presence of significant shared DNA between JR 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 Maria Giese to Anna Gartzke, and ultimately to JR, confirming this direct ancestral connection through multiple generations.
