The paternal relationship between David Luther Gettz and his daughter MBG is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DL.
The segmental (via DNA segment triangulation) and total DNA shared between DL and other confirmed descendants of
Charles Washington Gettz is consistent with the expected ranges for their respective relationships. Since DL descends from Charles Washington Gettz through David Luther Gettz and his daughter MBG, the presence of significant shared DNA between DL and other known descendants of Charles Washington Gettz validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA Charles Washington Gettz through David Luther Gettz to MBG, and ultimately to DL, confirming this direct ancestral connection through multiple generations.
