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