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