The maternal relationship between Ollie K. Henderson and her daughter Leila Gish 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 Ollie K. Henderson and her daughter Leila Gish, 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 Ollie K. Henderson to Leila Gish, and ultimately to MM, confirming this direct ancestral connection through multiple generations.
