Julius Jackson Cole Sr was the son of Loyd Cole. A big group of Coles moved from Wake County NC to the Humphreys County TN area about 1826. Loyd was the son of John Cole of Hillsborough, Wake County who was the son of Mark Cole who was a miller in Fayetteville. His father was Stephen Cole of Chester, PA.
Julius Jackson also had a son Julius Jackson Cole Jr.
(I am a descendant of Julius Sr. through his son Calvin Cole.)
