Arnprior is a heritage-listed homestead and farm at Mayfield Road, Larbert, Queanbeyan-Palerang Region, New South Wales, Australia. It was built from 1827 by William Ryrie. It was added to the New South Wales State Heritage Register on 18 November 1999. History Arnprior has associations with the Ryrie family, dating to the 1820s. Scottish-born Stewart Ryrie (1778–1852) immigrated to Australia in 1825 on board the Triton with his second wife Isabella Ryrie (née Cassels) and the six children from his first marriage. Ryrie's two eldest sons were William (born ) and James (born ). Stewart Ryrie had served as a deputy assistant commissary general in the British Army during the Peninsular War in 1808–1815, stationed in Spain and Portugal. On arrival to Sydney in October 1825, Ryrie took up an appointment as the deputy assistant commissary general, based at the Commissariat Stores at Circular Quay. On 22 September 1826, William and James Ryrie wrote to the Colonial Secretary Alexander Macleay, stating their intention to "reside on the Land to be granted to us" as they were unable to find suitable work in Sydney. In , William Ryrie was granted Portion 4 of the Parish of Larbert in the County of Murray. Ryrie's grant encompassed 2560 acres and was a roughly rectangular parcel of land located to the north of the Shoalhaven River and to the north-east of the Village of Larbert. It appears that Ryrie's grant had earlier been occupied by a William Bradbury. It appears that Bradbury held a Ticket of Occupation for the land he had been living on at Curraduck-bidgee (Kurraducbidgee) prior to 1826. 'Bradbury's Station' is shown on Robert Hoddle's 1824 map of the Braidwood District, roughly in the vicinity of Ryrie's grant. Bradbury later moved to the Bungonia area. William Ryrie's land grant was named Arnprior in memory of Isabella Ryrie (née Cassels)'s family home in Scotland. The 1828 Census indicates that a house on William's 2560-acre land grant, Arnprior, was under construction at this time, as was a house on his brother James's grant Durran Durra. The Census recorded that there were 18 people living at Arnprior including workforce of eleven (ten of whom were convicts or ex-convicts). It also recorded that there were 35 acres of cleared land and 23 acres cultivated land at Arnprior, compared to one acre cultivated and cleared land at Durran Durra. Arnprior had 553 head of cattle and 1100
