The paternal relationship between Henry Jackson and his son RJ is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JR.

The segmental (via DNA segment triangulation) and total DNA shared between JR and other confirmed descendants of JJ/EH is consistent with the expected ranges for their respective relationships. Since JR descends from JJ/EH through Henry Jackson and his son RJ, the presence of significant shared DNA between JR and other known descendants of JJ/EH validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple JJ/EH through Henry Jackson to RJ, and ultimately to JR, confirming this direct ancestral connection through multiple generations.
