Samuel Mobbs, a plasterer, was found guilty on 21 April 1784 at the Old Bailey, London, of stealing a cotton handkerchief worth one shilling. Sentenced to seven years transportation he was sent to the Censor hulk. He arrived in Sydney aboard the Scarborough in January 1788 as part of the First Fleet. On 8 January 1790 Mobbs was sent to Norfolk island on the Supply. By May he was sharing his resources with Martha Batley. In July 1791 he was subsisting two people (the other person being, presumably, Martha) on a one acre Sydney Town allotment. There is no further record of Mobbs at Norfolk Island. He may have left when his sentence expired in 1792.
