The maternal relationship between Billie Jean Keeling and her daughter CJC is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant PS.
The segmental (via DNA segment triangulation) and total DNA shared between PS and other confirmed descendants of
James Fulton Hatcher/
Catherine Elizabeth Martin is consistent with the expected ranges for their respective relationships. Since PS descends from James Fulton Hatcher/Catherine Elizabeth Martin through Billie Jean Keeling and her daughter CJC, the presence of significant shared DNA between PS 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 Billie Jean Keeling to CJC, and ultimately to PS, confirming this direct ancestral connection through multiple generations.
