The maternal relationship between Mary Eliza Peet and her daughter EAY is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant HC.

The segmental (via DNA segment triangulation) and total DNA shared between HC and other confirmed descendants of Isaac Sanford Smith/Mary Taylor is consistent with the expected ranges for their respective relationships. Since HC descends from Isaac Sanford Smith/Mary Taylor through Mary Eliza Peet and her daughter EAY, the presence of significant shared DNA between HC and other known descendants of Isaac Sanford Smith/Mary Taylor validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Isaac Sanford Smith/Mary Taylor through Mary Eliza Peet to EAY, and ultimately to HC, confirming this direct ancestral connection through multiple generations.
