The maternal relationship between Shirley Joyce Shipley and her DNA tested daughter SR is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between SR and other confirmed descendants of
Johann Radke/
Anna Gartzke is consistent with the expected ranges for their respective relationships. Since SR descends from Johann Radke/Anna Gartzke through Shirley Joyce Shipley, the presence of significant shared DNA between SR and other known descendants of Johann Radke/Anna Gartzke validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Johann Radke/Anna Gartzke through Shirley Joyce Shipley to SR, confirming this direct ancestral connection through multiple generations.
