The paternal relationship between Wilburn Guynatti Springer and his son
John Wilbur Springer is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant CS.
The segmental (via DNA segment triangulation) and total DNA shared between CS and other confirmed descendants of
Robert Brashears/
Sarah Rhea Hankins is consistent with the expected ranges for their respective relationships. Since CS descends from Robert Brashears/Sarah Rhea Hankins through Wilburn Guynatti Springer and his son John Wilbur Springer, the presence of significant shared DNA between CS and other known descendants of Robert Brashears/Sarah Rhea Hankins validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Robert Brashears/Sarah Rhea Hankins through Wilburn Guynatti Springer to John Wilbur Springer, and ultimately to CS, confirming this direct ancestral connection through multiple generations.
