The maternal relationship between Florence Marie Bieniewicz and her daughter BB is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant NB.

The segmental (via DNA segment triangulation) and total DNA shared between NB and other confirmed descendants of John Bieniewicz/Antonia Lewandowski is consistent with the expected ranges for their respective relationships. Since NB descends from John Bieniewicz/Antonia Lewandowski through Florence Marie Bieniewicz and her daughter BB, the presence of significant shared DNA between NB and other known descendants of John Bieniewicz/Antonia Lewandowski validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple John Bieniewicz/Antonia Lewandowski through Florence Marie Bieniewicz to BB, and ultimately to NB, confirming this direct ancestral connection through multiple generations.
