The maternal relationship between Elizabeth Henderson and her son
Henry George Alderson 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 Elizabeth Henderson and her son Henry George Alderson, 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 Elizabeth Henderson to Henry George Alderson, and ultimately to MM, confirming this direct ancestral connection through multiple generations.
