The paternal relationship between Thomas Jefferson Short and his son
William S. Short is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant KG.
The segmental (via DNA segment triangulation) and total DNA shared between KG and other confirmed descendants of
James Alexander Short/
Elizabeth Moore is consistent with the expected ranges for their respective relationships. Since KG descends from James Alexander Short/Elizabeth Moore through Thomas Jefferson Short and his son William S. Short, the presence of significant shared DNA between KG 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 Thomas Jefferson Short to William S. Short, and ultimately to KG, confirming this direct ancestral connection through multiple generations.
