Jacob Defehr (13 Nov 1780 - 1823)

The paternal relationship between Jacob Defehr and his son Isaac Defehr 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/AB is consistent with the expected ranges for their respective relationships. Since ED descends from Benjamin Defehr/AB through Jacob Defehr and his son Isaac Defehr, the presence of significant shared DNA between ED and other known descendants of Benjamin Defehr/AB validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Benjamin Defehr/AB through Jacob Defehr to Isaac Defehr, and ultimately to ED, confirming this direct ancestral connection through multiple generations.
