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