The maternal relationship between Helena Sawatzky and her son
Jacob John Fehr 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
Peter Sawatzky/
Margaretha Rempel is consistent with the expected ranges for their respective relationships. Since TCF descends from Peter Sawatzky/Margaretha Rempel through Helena Sawatzky and her son Jacob John Fehr, the presence of significant shared DNA between TCF and other known descendants of Peter Sawatzky/Margaretha Rempel validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Peter Sawatzky/Margaretha Rempel through Helena Sawatzky to Jacob John Fehr, and ultimately to TCF, confirming this direct ancestral connection through multiple generations.
