Elisabeth Isaak (10 Feb 1856 - 11 Nov 1922)

The maternal relationship between Elisabeth Isaak and her son David Koehn is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant CK.

The segmental (via DNA segment triangulation) and total DNA shared between CK and other confirmed descendants of MR is consistent with the expected ranges for their respective relationships. Since CK descends from MR through Elisabeth Isaak and her son David Koehn, the presence of significant shared DNA between CK and other known descendants of MR validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA MR through Elisabeth Isaak to David Koehn, and ultimately to CK, confirming this direct ancestral connection through multiple generations.
