The maternal relationship between Dora J Betz and her son
Frederick Betz Claussen is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant FC.
The segmental (via DNA segment triangulation) and total DNA shared between FC and other confirmed descendants of
George Martin Betz is consistent with the expected ranges for their respective relationships. Since FC descends from George Martin Betz through Dora J Betz and her son Frederick Betz Claussen, the presence of significant shared DNA between FC 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 Dora J Betz to Frederick Betz Claussen, and ultimately to FC, confirming this direct ancestral connection through multiple generations.
