The paternal relationship between Donald Lawrence Lawson Sr and his daughter CSL is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant CSL.

The segmental (via DNA segment triangulation) and total DNA shared between CSL and other confirmed descendants of JJLL/Stella Emeline MacCormac is consistent with the expected ranges for their respective relationships. Since CSL descends from JJLL/Stella Emeline MacCormac through Donald Lawrence Lawson Sr and his daughter CSL, the presence of significant shared DNA between CSL and other known descendants of JJLL/Stella Emeline MacCormac validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple JJLL/Stella Emeline MacCormac through Donald Lawrence Lawson Sr to CSL, and ultimately to CSL, confirming this direct ancestral connection through multiple generations.
