The paternal relationship between Cauis Marius Tompkins and his daughter Mary Ann Tompkins is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant PR.

The segmental (via DNA segment triangulation) and total DNA shared between PR and other confirmed descendants of Abram Tompkins/Mary Ann Eaton is consistent with the expected ranges for their respective relationships. Since PR descends from Abram Tompkins/Mary Ann Eaton through Cauis Marius Tompkins and his daughter Mary Ann Tompkins, the presence of significant shared DNA between PR 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 Cauis Marius Tompkins to Mary Ann Tompkins, and ultimately to PR, confirming this direct ancestral connection through multiple generations.
