convict ship

,So my convict ancestor is Henry Wells ( I see a relative is on this project. Although my ancestor is Henry Wells, it is still to be proven he came to VDL, as it is such a common name. My research has him arriving in Tasmania in 1827 aboard 'The Asia' 2. I have found his records etc. but we can't definitely link him as leaving Tasmania. We do know he turns up in Adelaide in 1849 and Sarah Ann Blackmore. A free woman who arrived in Adelaide just months before aboard the 'Mary Ann'. So where do i go from here? Do I link this person to te project? Maree
