The maternal relationship between Ann Murdoch and her son
Orson Edwin Giles is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant GG.
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 Ann Murdoch and her son Orson Edwin 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 Ann Murdoch to Orson Edwin Giles, and ultimately to GG, confirming this direct ancestral connection through multiple generations.
