The maternal relationship between Jacqueline Yvonne Porter and her DNA tested daughter DL is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between DL and other confirmed descendants of
Francis Francis/
Grace Roberts is consistent with the expected ranges for their respective relationships. Since DL descends from Francis Francis/Grace Roberts through Jacqueline Yvonne Porter, the presence of significant shared DNA between DL and other known descendants of Francis Francis/Grace Roberts validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Francis Francis/Grace Roberts through Jacqueline Yvonne Porter to DL, confirming this direct ancestral connection through multiple generations.
