Hello Shelley,
I hope you are A1 again.
Interesting that on 20/05/1846 a John LEE disembarked from the "Joseph Somes" in Hobart, having been transported for 7 years from Doncaster. After completing his servitude he sailed for Melbourne on 28/04/1852!!!
Both Ratcliff and Haggerston are essentially North Easternly areas of London, so a trial at the Central Criminal Court is highly feasible, but the age is a considerable problem, even allowing for atrocious record-keeping in those days, especially ages. Of course a lot of people only had vague ideas when they born!!
Then again did he tell a "fib", knowing that a younger age would earn preferential treatment in prison terms, such as Parkhurst, where there were no previous convictions to be taken into account, which he appears not to have had. Sadly, it all seems a little tenuous though...... the age worries me.
However, he must have arrived in Australia somehow and possibly the most fruitful sources to explore would be the Assisted/Unassisted arrivals records held by the PROV.
Do let me know.
For the moment,
Tony
