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