The maternal relationship between Linda Duncan and her DNA tested son CS is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between CS and other confirmed descendants of
Willie Franklin Duncan/
Alma Pearl Chalmers is consistent with the expected ranges for their respective relationships. Since CS descends from Willie Franklin Duncan/Alma Pearl Chalmers through Linda Duncan, the presence of significant shared DNA between CS and other known descendants of Willie Franklin Duncan/Alma Pearl Chalmers validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Willie Franklin Duncan/Alma Pearl Chalmers through Linda Duncan to CS, confirming this direct ancestral connection through multiple generations.
