Zardoc Cook, War of 1812 Georgia Veteran-- Part 1: Zadock or Zardoc?

From the November 8, 2017, Oconee Enterprise  "Descendant of War of 1812 veteran dedicates the homestead" Michael Prochaska.

Zardoc Cook, the 4th great grandfather of Joyce Lambeit was the veteran in question.  Lambeit belongs to the General John Baytop Scott Chapter U.S. Daughters which had the ceremony.  A historical marker will be put up at Cook's house.

Zadoc Cook was born February 18, 1769, in Halifax County, North Carolina, and died at age 96 on August 3, 1863, in Clarke County, now Oconee County, Georgia.

Upon further research on him, I have come across some confusion as to whether his first name is spelled Zadoc, Zardoc or Zardock.
