The maternal relationship between Dorothy Stevens Titcomb and her son KLJ is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant KLJ.

The segmental (via DNA segment triangulation) and total DNA shared between KLJ and other confirmed descendants of Howard Chessman Titcomb/Lorena Stubbs is consistent with the expected ranges for their respective relationships. Since KLJ descends from Howard Chessman Titcomb/Lorena Stubbs through Dorothy Stevens Titcomb and her son KLJ, the presence of significant shared DNA between KLJ and other known descendants of Howard Chessman Titcomb/Lorena Stubbs validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Howard Chessman Titcomb/Lorena Stubbs through Dorothy Stevens Titcomb to KLJ, and ultimately to KLJ, confirming this direct ancestral connection through multiple generations.
