The maternal relationship between Christina Defehr and her son
David Doerksen is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant APF.
The segmental (via DNA segment triangulation) and total DNA shared between APF and other confirmed descendants of
Benjamin Defehr/
Anna Bergen is consistent with the expected ranges for their respective relationships. Since APF descends from Benjamin Defehr/Anna Bergen through Christina Defehr and her son David Doerksen, the presence of significant shared DNA between APF and other known descendants of Benjamin Defehr/Anna Bergen validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Benjamin Defehr/Anna Bergen through Christina Defehr to David Doerksen, and ultimately to APF, confirming this direct ancestral connection through multiple generations.
