The maternal relationship between Shirley Ruth Shipley and her son
Edwin Farrington is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant EF.
The segmental (via DNA segment triangulation) and total DNA shared between EF and other confirmed descendants of
Johann Radke/
Anna Gartzke is consistent with the expected ranges for their respective relationships. Since EF descends from Johann Radke/Anna Gartzke through Shirley Ruth Shipley and her son Edwin Farrington, the presence of significant shared DNA between EF 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 Ruth Shipley to Edwin Farrington, and ultimately to EF, confirming this direct ancestral connection through multiple generations.
