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