The paternal relationship between Jack Jenkins and his son Cornelius Jenkins is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant TR.

The segmental (via DNA segment triangulation) and total DNA shared between TR and other confirmed descendants of Cornelius Jenkins/Phillis Howard is consistent with the expected ranges for their respective relationships. Since TR descends from Cornelius Jenkins/Phillis Howard through Jack Jenkins and his son Cornelius Jenkins, the presence of significant shared DNA between TR and other known descendants of Cornelius Jenkins/Phillis Howard validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Cornelius Jenkins/Phillis Howard through Jack Jenkins to Cornelius Jenkins, and ultimately to TR, confirming this direct ancestral connection through multiple generations.
