The maternal relationship between Maria Enns and her daughter TR is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DSMW.
The segmental (via DNA segment triangulation) and total DNA shared between DSMW and other confirmed descendants of JP is consistent with the expected ranges for their respective relationships. Since DSMW descends from JP through Maria Enns and her daughter TR, the presence of significant shared DNA between DSMW and other known descendants of JP validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA JP through Maria Enns to TR, and ultimately to DSMW, confirming this direct ancestral connection through multiple generations.
