The maternal relationship between Ethel May Shupe and her daughter Dorothy Ellen Jackson is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant HJ.

The segmental (via DNA segment triangulation) and total DNA shared between HJ and other confirmed descendants of Herman Rudolph Kruse/Catharina Maria Adelheid Redeker is consistent with the expected ranges for their respective relationships. Since HJ descends from Herman Rudolph Kruse/Catharina Maria Adelheid Redeker through Ethel May Shupe and her daughter Dorothy Ellen Jackson, the presence of significant shared DNA between HJ and other known descendants of Herman Rudolph Kruse/Catharina Maria Adelheid Redeker validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Herman Rudolph Kruse/Catharina Maria Adelheid Redeker through Ethel May Shupe to Dorothy Ellen Jackson, and ultimately to HJ, confirming this direct ancestral connection through multiple generations.
