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