The maternal relationship between Harriet Drayton and her son
Stephen Smalls is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant CA.
The segmental (via DNA segment triangulation) and total DNA shared between CA and other confirmed descendants of TD/A is consistent with the expected ranges for their respective relationships. Since CA descends from TD/A through Harriet Drayton and her son Stephen Smalls, the presence of significant shared DNA between CA and other known descendants of TD/A validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple TD/A through Harriet Drayton to Stephen Smalls, and ultimately to CA, confirming this direct ancestral connection through multiple generations.
