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