The maternal relationship between Marietta "Mary" Glasford and her son Clarence Tayler Herrick is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant CHS.

The segmental (via DNA segment triangulation) and total DNA shared between CHS and other confirmed descendants of Isaac M. Glasford/Diantha Matilda Devore is consistent with the expected ranges for their respective relationships. Since CHS descends from Isaac M. Glasford/Diantha Matilda Devore through Marietta "Mary" Glasford and her son Clarence Tayler Herrick, the presence of significant shared DNA between CHS and other known descendants of Isaac M. Glasford/Diantha Matilda Devore validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Isaac M. Glasford/Diantha Matilda Devore through Marietta "Mary" Glasford to Clarence Tayler Herrick, and ultimately to CHS, confirming this direct ancestral connection through multiple generations.
