Hi,
When/where was John born and what were his parents names?
Have you viewed or applied for any of his convict records from Australia? eg. Pardon

EDIT. this seems to his TOL index which gives us some clues
BURTON John Aurora 1833 42/655 Ticket of Leave [4/4160; Reel 943] District: Goulburn; Tried: Warwick assizes
