I just saw a reference in a British genealogical magazine to Transportation Records 1788-1868 which an online database listing Irish convicts transported to Australia (I spotted a New Zealand one in there too so there might be more). This database is provided by the National Archives of Ireland and is a searchable online database compiled from transportation registers and petitions to government for pardon. The results provide name, age, sex, place of imprisonment, trial date and description of their crime (often petty).

It is great to see another online database being provided by the National Archives of Ireland. it gives me hope!
