The maternal relationship between Margreth Fessler and her son
Matthew J Justin is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant GJ.
The segmental (via DNA segment triangulation) and total DNA shared between GJ and other confirmed descendants of
Johann Baptist Fessler/
Elisabetha Maria Schmitz is consistent with the expected ranges for their respective relationships. Since GJ descends from Johann Baptist Fessler/Elisabetha Maria Schmitz through Margreth Fessler and her son Matthew J Justin, the presence of significant shared DNA between GJ and other known descendants of Johann Baptist Fessler/Elisabetha Maria Schmitz validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Johann Baptist Fessler/Elisabetha Maria Schmitz through Margreth Fessler to Matthew J Justin, and ultimately to GJ, confirming this direct ancestral connection through multiple generations.
