The paternal relationship between Clarence Alfred Ackerson and his daughter HPA is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant TH.

The segmental (via DNA segment triangulation) and total DNA shared between TH and other confirmed descendants of Nels Nelson or Nils Ackerson/Hannah Hanna Larson is consistent with the expected ranges for their respective relationships. Since TH descends from Nels Nelson or Nils Ackerson/Hannah Hanna Larson through Clarence Alfred Ackerson and his daughter HPA, the presence of significant shared DNA between TH and other known descendants of Nels Nelson or Nils Ackerson/Hannah Hanna Larson validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Nels Nelson or Nils Ackerson/Hannah Hanna Larson through Clarence Alfred Ackerson to HPA, and ultimately to TH, confirming this direct ancestral connection through multiple generations.
