He was aged 20, single, could read and write and was from Tipperary.
On 20 March 1827 he had been convicted of abduction at Limerick and sentenced to transportation for life.
After arriving in Sydney, he was fortunate to be assigned to George Wyndham, a wealthy young pioneer vigneron in the Hunter Valley, north of Sydney.
George and his wife Margaret also arrived in Sydney in 1828 and bought a 2,000 acre property on the Hunter River.
Wyndham, who was only 27 himself at the time, later became renowned for being very kind to his assigned convict workers.
Patrick Brown was assigned to him as a servant.
[The Wyndham Estate is still in existence as a working wine-producing operation.]
On 23 September 1839, Patrick Brown, aged 31, was granted permission by Rev. John Fitzpatrick of Goulburn to marry "free emigrant", Catherine Rourke.
But just two weeks later, on 7 October 1839, this permission was withdrawn on the grounds that not enough information had been supplied about 'Cath'.
It would appear that the information withheld was that she, like Patrick, was a convict, not a 'free emigrant'.
Catherine Rourke arrived in Sydney on 23 April 1837 on the Sarah & Elizabeth after being sentenced to 14 years transportation at Lancaster, Liverpool Quarter Sessions.
That same year, Patrick had a son, Thomas, by an Aboriginal woman.
In 1844, Patrick Brown was granted a conditional pardon.
At that time he was assigned to Mr Campbell JP, the manager of a squatter's run on the south side of the Moruya River, near Broulee.
This was 'Gundary' owned by William Morris and located across the river from the farm of the first settler in the area, Francis Flanagan.
Patrick Brown was under the jurisdiction of three local magistrates and landholders: Francis Flanagan, John Hawdon and one other.
There is no marriage record for Patrick and Catherine, but in 1848 they appear to have had a son, John, and in 1859, another son James born at Broulee.
