The maternal relationship between Ethel Mae Tompkins and her son Carl Adrian Brown is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JH.

The segmental (via DNA segment triangulation) and total DNA shared between JH and other confirmed descendants of Abram Tompkins/Mary Ann Eaton is consistent with the expected ranges for their respective relationships. Since JH descends from Abram Tompkins/Mary Ann Eaton through Ethel Mae Tompkins and her son Carl Adrian Brown, the presence of significant shared DNA between JH 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 Ethel Mae Tompkins to Carl Adrian Brown, and ultimately to JH, confirming this direct ancestral connection through multiple generations.
