The maternal relationship between Martha Radke and her daughter
Esther Kissau is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant KL2.
The segmental (via DNA segment triangulation) and total DNA shared between KL2 and other confirmed descendants of
Johann Radke/
Anna Gartzke is consistent with the expected ranges for their respective relationships. Since KL2 descends from Johann Radke/Anna Gartzke through Martha Radke and her daughter Esther Kissau, the presence of significant shared DNA between KL2 and other known descendants of Johann Radke/Anna Gartzke validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Johann Radke/Anna Gartzke through Martha Radke to Esther Kissau, and ultimately to KL2, confirming this direct ancestral connection through multiple generations.
