The maternal relationship between Laura Irene Graham and her daughter LJW is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MD.

The segmental (via DNA segment triangulation) and total DNA shared between MD and other confirmed descendants of George Graham/Jane Morgan is consistent with the expected ranges for their respective relationships. Since MD descends from George Graham/Jane Morgan through Laura Irene Graham and her daughter LJW, the presence of significant shared DNA between MD and other known descendants of George Graham/Jane Morgan validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple George Graham/Jane Morgan through Laura Irene Graham to LJW, and ultimately to MD, confirming this direct ancestral connection through multiple generations.
