I do not have any of those, all skilled working class aristocracy in mine and proud of it, Scots non conformists, maybe it is the morality, but somehow going off the rails really never appealed.
There's many a non conformist Scot who was transported beyond the seas under sentence of a Scottish court
Those who were transported to Van Diemen's Land (Tasmania) have their details in the Tasmanian Archives. The convict records that those Archives hold are among the most detailed anywhere.
I have one Scottish ancestor who was transported to New South Wales. She was an arsonist. Her original sentence was commuted from one of death to one of life. Her NSW official records include details about her height, the colour of her hair, her eyes, her complexion and other personal details. I even know what clothing was supplied to her on embarking on the transport ship.
On the other hand, I do have Scottish ancestors who migrated to NSW several decades before "my" arsonist. Official records are scant on information about them.
I do agree with Ruskie re the mawkishness of TV programs offering all sorts of excuses and wild stories. Those excuses and wild stories develop a "life of their own" and so often become urban myths.
Some of the Tasmanian Archives Convict records show repeat offenders were in prisons in the UK several times before being sentenced to transportation. Other times the offence would in today's world result in a collective shrug of the shoulders. However, I find the TV programs often comment from a 21st Century viewpoint instead of attempting to understand the historical circumstances ..... for example, the development of Manufactories, the Enclosure of Commons, the Corn Laws, the Wesleyan Dissenters, the 18th and 19th Centuries understanding of the benefits of learning to read and to write, and soooooooooooooo many other topics.
