The paternal relationship between Robert Ratliff and his daughter
Margaret Ratliff is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MB.
The segmental (via DNA segment triangulation) and total DNA shared between MB and other confirmed descendants of
Thomas Harper Ratliff/
Lucy Johnson is consistent with the expected ranges for their respective relationships. Since MB descends from Thomas Harper Ratliff/Lucy Johnson through Robert Ratliff and his daughter Margaret Ratliff, the presence of significant shared DNA between MB and other known descendants of Thomas Harper Ratliff/Lucy Johnson validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Thomas Harper Ratliff/Lucy Johnson through Robert Ratliff to Margaret Ratliff, and ultimately to MB, confirming this direct ancestral connection through multiple generations.
