Australian Royalty
Britain used transportation to distant lands as a way of getting rid of prisoners. After Britain lost its American colonies in 1783 the jails of England were full. So, Australia, which had recently been claimed for the British Crown by Lieutenant James Cook, was chosen as the new destination.

Only a generation or so ago, descendants of convicts were ashamed of their heritage. However, since the 1988 bicentenary, it has become increasingly fashionable to discover a convict ancestor. Early arrivals, especially on the first fleet, were particularly welcome finds with convict ancestry one of the most sought-after prizes of genealogical inquiry.

Then, in January 2008, the first episode of the first season of the Australian version of the television series, "Who do you think you are"?, featured Australian award-winning actor, Jack Thompson, who quipped that, "these day, unlike times gone by, having a convict ancestor gives you the status of Australian royalty".

The most prestigious genealogical group is the Fellowship of the First Fleeters. Only 113 of the 788 original convicts have descendants living in Australia today.

The Fourth Fleet was a fleet of 3 British ships that brought British colonists and convicts to Australia, departing Portsmouth, England on the 14 February 1792. The fleet was made up of:
- Pitt (Departed June 1791, arrived Sydney 14 February 1792),
- Kitty (arrived 6 April 1792).
- Royal Admiral (arrived Sydney 7 October 1792).

William Singleton, convicted for stealing in London, was in the Fourth Fleet. Aboard the, "Pitt", with 403 other convicts, arrived in Sydney Cove (present day Circular Quay in Sydney), New South Wales, on the 14 February 1792.

Month of death, from a Newspaper article in the Singleton Argus of Friday 7 June 1935, that mentions the father of Benjamin Singleton, William Singelton, and found in March 2024 on the National Library of Australia’s Trove website:
Later on Benjamin, Senr., brought his aged father to reside here [Patrick's Plains], and in May, 1835, the old gentleman passed peacefully away at the ripe old age of 90 years. It has been stated that he was buried in the plot in which his son's house in John street was situated. There is nothing extraordinary in that, for it was quite a common thing in the long ago, and even at the present time is occasionally practiced.
