Thomas Duffett (baptised 1785 Stalbridge, Dorset, England) had a couple of run-ins with the law and got himself sentenced to 7 years transportation. Twice. But he never left the country.
The first time around, in December 1816, he was sentenced to death for sheep stealing. The sentence was commuted to 7 years transportation and he was transferred to the prison hulk Laurel in Portsmouth Harbour in May 1817. He next shows up in the Prison Hulk registers, first in the Laurel and then in the York. The York register shows his 'disposal' as PFP (which means a Free Pardon); the date is not very legible but looks like sometime in 1821 (which ties in with the fact that he had children born in early 1817 and then 1822).
In January 1849 he was again sentenced to 7 years transportation, for stealing timber this time. The Sherborne Mercury in October 1849 includes reference to the fact that the Government had rejected him as unfit to go on account of ill-health and the Secretary of State might be asked to remit his sentence. The Dorchester Prisons admission and discharge register shows an annotation after his original sentence of transportation showing that it was commuted to 2 years hard labour, and he was back home in time for the 1851 census in Stalbridge.
He died in 1856 in the Sturminster Union Poorhouse and was buried at Stalbridge Parish Church.
So: what determined that he spent about 4 years imprisoned in England from 1817-1821 and then received a Free pardon, when other prisoners in the same period were being transported? And what would render a man unfit for transportation in 1849, although he survived 2 years hard labour instead and survived another 5 years after that?
