David Defehr (ABT 1792 - Dec 1860)

The paternal relationship between David Defehr and his son David Fehr is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant TF.

The segmental (via DNA segment triangulation) and total DNA shared between TF and other confirmed descendants of Benjamin Defehr/AB is consistent with the expected ranges for their respective relationships. Since TF descends from Benjamin Defehr/AB through David Defehr and his son David Fehr, the presence of significant shared DNA between TF 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 David Defehr to David Fehr, and ultimately to TF, confirming this direct ancestral connection through multiple generations.
