The maternal relationship between Katharina Braun and her son
Jacob W. Friesen is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant LF.
The segmental (via DNA segment triangulation) and total DNA shared between LF and other confirmed descendants of
Johann Sawatzky/
Susanna "sanke" Entz is consistent with the expected ranges for their respective relationships. Since LF descends from Johann Sawatzky/Susanna "sanke" Entz through Katharina Braun and her son Jacob W. Friesen, the presence of significant shared DNA between LF and other known descendants of Johann Sawatzky/Susanna "sanke" Entz validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Johann Sawatzky/Susanna "sanke" Entz through Katharina Braun to Jacob W. Friesen, and ultimately to LF, confirming this direct ancestral connection through multiple generations.
