ARRIVAL IN PORT JACKSON
The Brothers arrived in Port Jackson on 4 February 1827, a voyage of 122 days. A muster was held on board by Colonial Secretary Alexander McLeay on 7th February 1827.
The indents include name, age, education, religion, marital status, family, native place, trade, offence, date and place of trial, sentence, prior convictions, physical description and where and to whom the women were assigned on arrival. There is also occasional information regarding relatives already in the colony, deaths and colonial crimes.
Ninety five of the prisoners were single women, all of child bearing age although only nine were recorded as having children. Many of the women had left children behind in Ireland. Those who brought children on the voyage with them included:
Isabella Allison; Julian or Judith Burke; Mary Buttler; Honorah Carthy; Mary Jackson; Mary Lynch; Ellen Murphy; Ellen Ramsey; Honora Reardon; Martha Sadler; Ann Smith alias Ferguson; Jane Taafe; and Mary or Margery Treel.
One of the prisoners, Ann Byrne was supposed to have come on the Lady Rowena however had the remark 'not embarked' beside her name. She was tried in Dublin on 18th August 1825 and sentenced to 7 years transportation. Bridget Leonard was tried at the same time for the same offence. Bridget Leonard was transported on the Lady Rowena however Ann Byrne came on the Brothers. She was later required to prove her identity as the indent on the Brothers stated she was a prisoner for life instead of 7 years.
After they were disembarked the prisoners were either assigned privately to settlers or sent to the Female Factory at Parramatta.
DEPARTURE OF THE BROTHERS
After disembarking the prisoners the Brothers was engaged to sail to Batavia - The Sydney Monitor recorded the attempted voyage:
Captain Motley of the Brothers on returning to port, after an ineffectual attempt to make the Western Passage through Torres Straits to Batavia, spoke of the weather he experienced as dreadful beyond description; such as during his course of Navigation he had never before experienced; for 50 hours his vessel laboured under a heavy gale, which Capt. M. believes to have strained and otherwise injured her, more than an ordinary passage from England to New South Wales and back again would have done. Notwithstanding all these difficulties he continued his endeavours to beat round the land with extraordinary determination, till at length Hope forsook him, and the safety of crew and vessel compelled him to shape his course back to Port Jackson. She resumed her voyage on Tuesday last.
The Brothers was one of five convict ships bringing female prisoners to New South Wales in 1827, however she was the only vessel bringing Irish convicts in that year. The other female convict ships arriving in 1827 were the Grenada, Princess Charlotte, Louisa, and Harmony. Over five hundred female prisoners arrived in the colony in 1827.
James Forrester was also employed as surgeon superintendent on the convict ships Southworth in 1832 and lost his life on the ill-fated voyage of the Amphitrite in 1833.
