The paternal relationship between Reason T Sandifer and his son
Randall Thomas 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 Reason T Sandifer and his son Randall Thomas 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 paternal line.
This supports the conclusion that DNA was passed from MRCA couple Robert III Chapman/Elizabeth Leah Taylor through Reason T Sandifer to Randall Thomas Sandifer, and ultimately to JK, confirming this direct ancestral connection through multiple generations.
