The maternal relationship between Marie Lukens and her son
James Richard Hart is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant BJ.
The segmental (via DNA segment triangulation) and total DNA shared between BJ and other confirmed descendants of
Thomas Harvey Lukens/
Mary Ann Hagy is consistent with the expected ranges for their respective relationships. Since BJ descends from Thomas Harvey Lukens/Mary Ann Hagy through Marie Lukens and her son James Richard Hart, the presence of significant shared DNA between BJ and other known descendants of Thomas Harvey Lukens/Mary Ann Hagy validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Thomas Harvey Lukens/Mary Ann Hagy through Marie Lukens to James Richard Hart, and ultimately to BJ, confirming this direct ancestral connection through multiple generations.
