The maternal relationship between Leila Gish and her daughter Esther LIllian Armstrong is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MM.

The segmental (via DNA segment triangulation) and total DNA shared between MM and other confirmed descendants of David Eaton Henderson/Elizabeth Gano is consistent with the expected ranges for their respective relationships. Since MM descends from David Eaton Henderson/Elizabeth Gano through Leila Gish and her daughter Esther LIllian Armstrong, the presence of significant shared DNA between MM and other known descendants of David Eaton Henderson/Elizabeth Gano validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple David Eaton Henderson/Elizabeth Gano through Leila Gish to Esther LIllian Armstrong, and ultimately to MM, confirming this direct ancestral connection through multiple generations.
