The paternal relationship between John Manley Norris and his son TN is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant TN.

The segmental (via DNA segment triangulation) and total DNA shared between TN and other confirmed descendants of Bernard "barney" R Cain is consistent with the expected ranges for their respective relationships. Since TN descends from Bernard "barney" R Cain through John Manley Norris and his son TN, the presence of significant shared DNA between TN and other known descendants of Bernard "barney" R Cain validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA Bernard "barney" R Cain through John Manley Norris to TN, and ultimately to TN, confirming this direct ancestral connection through multiple generations.
