The maternal relationship between Fern Louise Ackerson and her DNA tested daughter BL is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between BL and other confirmed descendants of
Nels Nelson or Nils Ackerson/
Hannah Hanna Larson is consistent with the expected ranges for their respective relationships. Since BL descends from Nels Nelson or Nils Ackerson/Hannah Hanna Larson through Fern Louise Ackerson, the presence of significant shared DNA between BL and other known descendants of Nels Nelson or Nils Ackerson/Hannah Hanna Larson validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Nels Nelson or Nils Ackerson/Hannah Hanna Larson through Fern Louise Ackerson to BL, confirming this direct ancestral connection through multiple generations.
