The maternal relationship between Edna Mixer and her son WS is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant LHD.
The segmental (via DNA segment triangulation) and total DNA shared between LHD and other confirmed descendants of
Margaret Hartman is consistent with the expected ranges for their respective relationships. Since LHD descends from Margaret Hartman through Edna Mixer and her son WS, the presence of significant shared DNA between LHD and other known descendants of Margaret Hartman validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA Margaret Hartman through Edna Mixer to WS, and ultimately to LHD, confirming this direct ancestral connection through multiple generations.
