Hi, it's been forever since I've done any searching of family history so apologies if I am going about this incorrectly.
I have recently learnt that an ancestor of mine, George Smith, was a convict who was transported to Australia on the Marquis of Hastings (2) in 1827, aged 24. (NOT to be confused with the other George Smith alias King who also traveled on the same boat!)
One site states that he was Brighthelmstone (?) but silly me didn't bookmark the site and I can't find that information again.

I have also found that he was apparantly tried at Lewes 19 December, 1825. Another site states that he was convicted at Sussex Special Session of Gaol Delivery. Are these the same thing? If not, what do these mean?
I would love it if someone could look these up, but understand if it's too much. At the very least I would love to understand what these documents are and the type of information that would be included. With such a common name, I know I don't have much of a hope of going any further back to finding his parents, etc. but trying to understand his crime and what it was would help colour in this ancestor of mine.
Kind regards,
Jen
