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