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