The paternal relationship between Emil Grade and his daughter
Wilhemine Augusta Grade is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant AF.
The segmental (via DNA segment triangulation) and total DNA shared between AF and other confirmed descendants of
Christian Ludwig Glander/
Anna Christina Wojahn is consistent with the expected ranges for their respective relationships. Since AF descends from Christian Ludwig Glander/Anna Christina Wojahn through Emil Grade and his daughter Wilhemine Augusta Grade, the presence of significant shared DNA between AF and other known descendants of Christian Ludwig Glander/Anna Christina Wojahn validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Christian Ludwig Glander/Anna Christina Wojahn through Emil Grade to Wilhemine Augusta Grade, and ultimately to AF, confirming this direct ancestral connection through multiple generations.
