The maternal relationship between Sylvia Leah Betts and her daughter SS is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant SS.

The segmental (via DNA segment triangulation) and total DNA shared between SS and other confirmed descendants of Abram Tompkins/Mary Ann Eaton is consistent with the expected ranges for their respective relationships. Since SS descends from Abram Tompkins/Mary Ann Eaton through Sylvia Leah Betts and her daughter SS, the presence of significant shared DNA between SS and other known descendants of Abram Tompkins/Mary Ann Eaton validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Abram Tompkins/Mary Ann Eaton through Sylvia Leah Betts to SS, and ultimately to SS, confirming this direct ancestral connection through multiple generations.
