The maternal relationship between Martha Frances Pennington and her daughter
Letha Belle Tucker is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant KD.
The segmental (via DNA segment triangulation) and total DNA shared between KD and other confirmed descendants of
James Chapman/
Ruth Bertha Hammer is consistent with the expected ranges for their respective relationships. Since KD descends from James Chapman/Ruth Bertha Hammer through Martha Frances Pennington and her daughter Letha Belle Tucker, the presence of significant shared DNA between KD and other known descendants of James Chapman/Ruth Bertha Hammer validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple James Chapman/Ruth Bertha Hammer through Martha Frances Pennington to Letha Belle Tucker, and ultimately to KD, confirming this direct ancestral connection through multiple generations.
