SURGEON HENRY KELSALL
Henry Kelsall kept a Medical Journal from 10 November 1836 to 10 June 1837. His previous voyage as surgeon on the Andromeda in 1834 which also brought female prisoners from Ireland, was a very different experience to this voyage of the Margaret. The women of the Andromeda were embarked in a clean condition and were healthy and in good spirits for most of the voyage. In contrast the prisoners of the Margaret disgusted him by their offensive habits and reluctance to keep clean.
His antipathy towards the women was evident from the time they were first embarked. He remarked in his journal that the women were all sent on board in a very filthy state from the Cork Penitentiary - with a small supply of spare clothing (linen). A great number were infected with psora as well as with influenza which was prevalent at the time in England and Ireland. A number of the crew were also affected.
Bilious fever became a problem when the ship reached the warmer climate. The surgeon also mentioned that most of the convicts if permitted passed the whole of the day in bed and collected all kinds of rubbish about them. He was appalled with another filthy habit of the convicts which he found difficult to stop - that of washing their linen in putrid urine which they would hang up to dry in the prison. Two convicts and five of their children died on the voyage out.  The two convicts were Rose Dogherty and Margaret Murphy.
Those treated by the surgeon during the voyage included:
Catherine Hurley, aged 21;
Eliza Wilson, aged 31;
FAnne Lawlor, aged 25;
Mary Maher, aged 24;

Passengers included Mr. Benson, Paymaster of the 28th Regiment, Mrs. Benson and Thomas Benson.
There twenty-five emigrants in the steerage. Mary Tobin aged 24, a free girl, was employed as servant to Mrs. Benson.
Henry Kelsall was no less scathing of the Irish free women and children of which he thought there were too many in the ship. He found them incorrigible and incredibly filthy. Most of these people were embarked in rags without a change of clothes of any description; and loaded with vermin - some of them mendicants by profession. 
The Margaret arrived in Port Jackson on 30 May 1837 and the women were landed at the Dockyard on 10th June 1837.
The convict indents include name, age, education, marital status, family, native place, trade, offence, previous convictions and physical description.
