Wow, that was quick! And a big thank you, as what you say makes perfect sense. My convict was reasonably wealthy and had inherited, bought and sold several land parcels. He lost it c1814-1818 when prices fell, and from 'gay living', and went to London to seek work only to become caught up in a shonky deal. His petitions were supported by Sir Joseph Banks, very well known in Australian history, among many other important local people. All to no avail: he died penniless in a Sydney asylum. So, that saves me much fruitless searching. Again thank you.
