The maternal relationship between Leah Elvira Chapman and her son
Reason T Sandifer is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JK.
The segmental (via DNA segment triangulation) and total DNA shared between JK and other confirmed descendants of
Robert III Chapman/
Elizabeth Leah Taylor is consistent with the expected ranges for their respective relationships. Since JK descends from Robert III Chapman/Elizabeth Leah Taylor through Leah Elvira Chapman and her son Reason T Sandifer, the presence of significant shared DNA between JK and other known descendants of Robert III Chapman/Elizabeth Leah Taylor validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Robert III Chapman/Elizabeth Leah Taylor through Leah Elvira Chapman to Reason T Sandifer, and ultimately to JK, confirming this direct ancestral connection through multiple generations.
