Surgeon James Bowman
Four prisoners died on the voyage.
There is no surgeon's journal available for the Lord Eldon, however James Bowman kept a journal on the voyage of the John Barry in 1819 and his methods for organizing the prisoners were probably similar on this voyage.
On the John Barry men were appointed to the various duties necessary for them to attend during the voyage. Three cooks, three hospital men, one to wash for the hospital; one boatswain of the prison and two boatswain mates; eight deck clearers, four swabbers, four sweepers, two to fill the cisterns with water, one to have charge of the windsails; two barbers, twenty four hatchmen for the prison, four to be on duty at a time and relieved every two hours, these men to be answerable for anything that may occur in the prison day or night, and report to sentries in the hatchways every half hour. Three teachers were appointed to attend to the school. The convicts were to sleep four in each berth, six to mess together and one to be caterer of the mess and receive the provisions. Two delegates from the convicts to see the ship's steward serve the provisions, to be answerable for the quantities issued, and to be changed every day. The beds, blankets and clothing were marked according to each man's number on the embarkation list .
Two hundred and fifteen male prisoners arrived in Port Jackson on the Lord Eldon on 30 September 1817. 
A strange sight greeted those who came to the Sydney docks to witness the arrival of the ship. From glass houses erected on deck emerged a fine selection of camellias and roses interspersed with fruit trees such as figs, oranges, plum, lemons, quinces, grapes, pomegranate, guavas and olives. Macarthur's diary notes that he had olives in four pots and two olive plants from Provence.

1). James Bowman was also surgeon on the convict ships Mary Anne in 1816 and the John Barry in 1819
James Freeman arrived as a convict on the Lord Eldon. He was sent to work at the limeburner gang and after absconding was punished in 1819. He later married and settled down near Norah Head where he ran a dairy on land owned by Robert Henderson. His premises were visited by the Jewboy gang in 1840.
James Woodley gained notoriety for his part in piratically stealing the pilot boat at Newcastle with several other felons. They were chased into Rushcutters Bay 60 miles to the south. A wanted notice was posted soon afterwards, however he probably remained at large until January 1822 when he gave himself up under a Proclamation by Sir Thomas Brisbane and was sent to Port Macquarie.
