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