The Roslin Castle
was built at Bristol in 1819. Convicts were transported to Australia on the Roslin Castle

George Imlay kept a Medical Journal which began on the 10th August when the guard boarded the vessel at Deptford. 
The Guard consisted of 30 rank and file of the 21st regiment accompanied by four women and four children under the command of Lieutenant Bayley. Other passengers included Mrs. Bayley and child and Lieutenant Pieter Laurenz Campbell
of the 21st Fusiliers. The Roslin Castle
left Deptford for Ireland two days later, however were obliged to put into Plymouth because of stormy weather, and did not arrived at Kingstown harbour until 7th September 1832.
ESSEX HULK - KINGSTOWN HARBOUR
Cholera was still raging in Dublin and it was reported that two men had died on the Essex hulk.
According to Parliamentary Papers 1838, John Lamb, age 50 was the keeper on the Essex and had been employed there for 17 years at a salary of £184 12s 4d. per annum and therefore was keeper of the gaol in 1833. 
CONVICTS EMBARKED AT DUBLIN
On 11th September one hundred and fifty two prisoners and eight free settlers were embarked on the Roslin Castle
and the vessel weighed anchor and put out to sea immediately to prevent communication between prisoners and their friends with the hope of lessening the chance of infection. After a stormy passage of five days when many of prisoners became ill with sea sickness and some showed signs of cholera, the vessel arrived at Cork Harbour. Seven men who were still ill were removed to the Surprise Hulk at Cork.
The Roslin Castle
sailed from Cork harbour on 8th October 1832 with 195 prisoners and five free settlers - Patrick Whalan, James Macgrogan, Patrick Neale, Terence Neale and James Slattery.
SURGEON GEORGE IMLAY
In the early days of the voyage George Imlay had to deal with dysentery, ophthalmia, and catarrh. Scurvy made an appearance amongst the men after only a month at sea. Nearly one third of the men were affected. Seventeen year old Lawrence Madden was the first case and seemed to be the most serious. He was put on the sick list on 11 November 1832 and discharged to hospital on 10 February 1833, five days after arrival in the colony. There was one death on the voyage, just one day of making land at Sydney.
As on the Dunvegan Castle
and the Eliza
, a number of prisoners on the Roslin Castle had been found guilty of Whiteboy crimes..........The Whiteboys (Irish: Buachaillí Bána) were a secret Irish agrarian organization in 18th-century Ireland which used violent tactics to defend tenant farmer land rights for subsistence farming. Their name derives from the white smocks the members wore in their nightly raids, but the Whiteboys were usually referred to at the time as Levellers by the authorities.
The Roslin Castle
arrived in Port Jackson on 5 February 1833.
A Muster was held on board by the Colonial Secretary on 8th February 1833. The indents reveal the name, age, education, religion, marital status, family, native place, occupation, crime, date and place of trial and physical description. Where and to whom the convicts were assigned on arrival in New South Wales is not revealed in the indents however many can be found in assignment lists in the Sydney Gazette
There were a number of very young convicts on this voyage. Six were 16 years old; one was 15; one 14; and four were only 13 years of age.
The male prisoners who arrived on the Roslin Castle
were landed immediately after the female prisoners of the Fanny
. It was reported that the men appeared in a good state of health; as many of them were good farm labourers, it was thought they would be an acquisition to the settlers.
About sixty of the Roslin Castle
prisoners have been identified residing in the Hunter Valley region in following years. Select here

The Roslin Castle
was laid on for Madras in March and was to convey the remainder of the 39th regiment.
