The maternal relationship between Deborah Bucknam and her son
William Titcomb 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
William Pote/
Dorothy Gatchell is consistent with the expected ranges for their respective relationships. Since KLJ descends from William Pote/Dorothy Gatchell through Deborah Bucknam and her son William Titcomb, the presence of significant shared DNA between KLJ and other known descendants of William Pote/Dorothy Gatchell validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple William Pote/Dorothy Gatchell through Deborah Bucknam to William Titcomb, and ultimately to KLJ, confirming this direct ancestral connection through multiple generations.
