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