The maternal relationship between Christine Elizabeth Robinson and her son
Albert Thomas Watson is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant WJW.
The segmental (via DNA segment triangulation) and total DNA shared between WJW and other confirmed descendants of
Preston S. Robinson/
Jane H. Jackson is consistent with the expected ranges for their respective relationships. Since WJW descends from Preston S. Robinson/Jane H. Jackson through Christine Elizabeth Robinson and her son Albert Thomas Watson, the presence of significant shared DNA between WJW and other known descendants of Preston S. Robinson/Jane H. Jackson validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Preston S. Robinson/Jane H. Jackson through Christine Elizabeth Robinson to Albert Thomas Watson, and ultimately to WJW, confirming this direct ancestral connection through multiple generations.
