The maternal relationship between Betty Jane Rohde and her daughter SG is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DS.
The segmental (via DNA segment triangulation) and total DNA shared between DS and other confirmed descendants of
Wilhelm Friedrich Rohde/
Wilhelmine Petzold is consistent with the expected ranges for their respective relationships. Since DS descends from Wilhelm Friedrich Rohde/Wilhelmine Petzold through Betty Jane Rohde and her daughter SG, the presence of significant shared DNA between DS and other known descendants of Wilhelm Friedrich Rohde/Wilhelmine Petzold validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Wilhelm Friedrich Rohde/Wilhelmine Petzold through Betty Jane Rohde to SG, and ultimately to DS, confirming this direct ancestral connection through multiple generations.
