The paternal relationship between Edgar Grant Tompkins and his son Gordon Mills Tompkins is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MH.

The segmental (via DNA segment triangulation) and total DNA shared between MH and other confirmed descendants of Abram Tompkins/Mary Ann Eaton is consistent with the expected ranges for their respective relationships. Since MH descends from Abram Tompkins/Mary Ann Eaton through Edgar Grant Tompkins and his son Gordon Mills Tompkins, the presence of significant shared DNA between MH and other known descendants of Abram Tompkins/Mary Ann Eaton validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Abram Tompkins/Mary Ann Eaton through Edgar Grant Tompkins to Gordon Mills Tompkins, and ultimately to MH, confirming this direct ancestral connection through multiple generations.
