The paternal relationship between Erwin Rohde and his daughter Betty Jane Rohde is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JS.

The segmental (via DNA segment triangulation) and total DNA shared between JS and other confirmed descendants of Wilhelm Friedrich Rohde/Wilhelmine Petzold is consistent with the expected ranges for their respective relationships. Since JS descends from Wilhelm Friedrich Rohde/Wilhelmine Petzold through Erwin Rohde and his daughter Betty Jane Rohde, the presence of significant shared DNA between JS and other known descendants of Wilhelm Friedrich Rohde/Wilhelmine Petzold validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Wilhelm Friedrich Rohde/Wilhelmine Petzold through Erwin Rohde to Betty Jane Rohde, and ultimately to JS, confirming this direct ancestral connection through multiple generations.
