I believe that John had a previous marriage and had a son. In the 1820 census John has a wife, a 16-26 y/o male and a newborn. I believe Wm. E. is the newborn. As John and Sarah did not have a son named John, I believe the 16-26 y/o in the 1820 census is John Jr. By the 1830 census, John Jr (?) is gone however we have found a John Cannady that obtains land in the Cherokee Land Lottery as did a Caleb Kennedy. Caleb and Mary Polly Evans, his wife moved to now Tallapoosa County Alabama. Caleb died in Tall. Co. and Mary Polly died in Coosa Co. One of John Sr.'s other sons, my Daniel Berrian Cannady had a son named John Lewis Caleb Cannady. Passing down names were so important to the men (and women) of those days.
