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 WTD.

The segmental (via DNA segment triangulation) and total DNA shared between WTD and other confirmed descendants of Solomon "Salmon" Mixer/Margaret Hartman is consistent with the expected ranges for their respective relationships. Since WTD descends from Solomon "Salmon" Mixer/Margaret Hartman through Edna Mixer and her son WS, the presence of significant shared DNA between WTD and other known descendants of Solomon "Salmon" Mixer/Margaret Hartman validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Solomon "Salmon" Mixer/Margaret Hartman through Edna Mixer to WS, and ultimately to WTD, confirming this direct ancestral connection through multiple generations.
