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