The maternal relationship between Lawanna Giles and her DNA tested son GG is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between GG and other confirmed descendants of
John Murray Murdoch is consistent with the expected ranges for their respective relationships. Since GG descends from John Murray Murdoch through Lawanna Giles, the presence of significant shared DNA between GG and other known descendants of John Murray Murdoch validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA John Murray Murdoch through Lawanna Giles to GG, confirming this direct ancestral connection through multiple generations.
