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