The maternal relationship between Ethel Amelia Riddle and her son
James Kenneth Watson is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant WJW.
The segmental (via DNA segment triangulation) and total DNA shared between WJW and other confirmed descendants of
James Fulton Hatcher/
Catherine Elizabeth Martin is consistent with the expected ranges for their respective relationships. Since WJW descends from James Fulton Hatcher/Catherine Elizabeth Martin through Ethel Amelia Riddle and her son James Kenneth Watson, the presence of significant shared DNA between WJW and other known descendants of James Fulton Hatcher/Catherine Elizabeth Martin validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple James Fulton Hatcher/Catherine Elizabeth Martin through Ethel Amelia Riddle to James Kenneth Watson, and ultimately to WJW, confirming this direct ancestral connection through multiple generations.
