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