David Fehr (ABT 1916 - 29 Jul 2003)

The paternal relationship between David Fehr and his son RDF 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 Johann Wall is consistent with the expected ranges for their respective relationships. Since TF descends from Johann Wall through David Fehr and his son RDF, the presence of significant shared DNA between TF and other known descendants of Johann Wall validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA Johann Wall through David Fehr to RDF, and ultimately to TF, confirming this direct ancestral connection through multiple generations.
