As you see there are a couple of slight discrepancies but the date of the trial remains the same and the name of the victim is the same, for the records for Charles CANNON/George CANNON. The names of his father, his siblings and his birthplace are the same.
I think you are safe to say that they are the same person. A clue may lie in the statement from the Indent -
"denies being in prison or being transported before." There is a conviction for a Charles CANNON, 18, for larceny at The Old Bailey in 1829, and was sentenced to 7 years transportation but I can see no Australian convict record for a matching Charles CANNON. Many sentences were reduced, so he may have been released rather than transported or transported elsewhere..
If they are the same man it would be in his interest to deny a previous conviction.
