The paternal relationship between Morris Smalls J and his son JMB is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JMB.

The segmental (via DNA segment triangulation) and total DNA shared between JMB and other confirmed descendants of Harry Jenkins/Susan Simmons is consistent with the expected ranges for their respective relationships. Since JMB descends from Harry Jenkins/Susan Simmons through Morris Smalls J and his son JMB, the presence of significant shared DNA between JMB and other known descendants of Harry Jenkins/Susan Simmons validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Harry Jenkins/Susan Simmons through Morris Smalls J to JMB, and ultimately to JMB, confirming this direct ancestral connection through multiple generations.
