Barbara Jean Clark (15/04/1935 - 06/04/2018)

The maternal relationship between Barbara Jean Clark and her DNA tested daughter SC is confirmed by the direct inheritance path of autosomal DNA.

The segmental (via DNA segment triangulation) and total DNA shared between SC and other confirmed descendants of David Calhoun Ratliff/Hepzibah Illinois Waddill is consistent with the expected ranges for their respective relationships. Since SC descends from David Calhoun Ratliff/Hepzibah Illinois Waddill through Barbara Jean Clark, the presence of significant shared DNA between SC and other known descendants of David Calhoun Ratliff/Hepzibah Illinois Waddill validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple David Calhoun Ratliff/Hepzibah Illinois Waddill through Barbara Jean Clark to SC, confirming this direct ancestral connection through multiple generations.
