David Reid (1820-1906) and Robert Dyce (1829-1900), pastoralists and politicians, were the first and third sons of David Reid, naval surgeon, and his wife Agnes, née Dyce. David was born probably at Plymouth, England, in December 1820. He came to New South Wales on 24 October 1823 in the Mariner with his parents and two sisters. The family settled at Inverary Park, near Bungonia. At first educated at home, he attended J. D. Lang's Australian College from 1831 and The King's School from 1834. Leaving school at 16, he took charge of his father's run in the Maneroo (Monaro) District but after meeting the overlander John Gardiner he decided to look for land south of the Murray River. Equipped by his father with some 500 head of cattle, 2 bullock wagons and teams and 6 assigned servants, he reached the Ovens River on 8 September 1838 the same day as Rev. Joseph Docker.
David settled at Currargarmonge, near Wangaratta, held at first in his father's name and after 1840 as a family partnership; despite an attempted attack by Aboriginals he harvested the first wheat crop in December 1839. At the end of 1843 he took up land near Yackandandah. After his marriage to Mary Romaine Barber on 29 February 1844 at Marulan, New South Wales, he left the partnership and in 1847 took up a section of the family run of which Woorajay (Wooragee) formed a part. He built the first water driven flour-mill in the district on his Yackandandah run in 1845; his woolclip of 1848 was one of the first to be handled by R. Goldsbrough and was claimed to come from sheep descended from stock imported in the 1820s from George III's flock.
In 1852 gold was discovered in the May Day Hills, and the Ovens gold rush settlements of Beechworth, El Dorado, Woolshed, Sebastopol and Reid's Creek developed on Reid family land, ruining its pastoral value. For a time David sold meat to the miners and ran the mill, a store and a gold-buying business, but in 1853 sold his runs and turned profitably to cattle and horse-dealing and general trading between Melbourne and the Riverina and the diggings. In November 1856 he bought the lease of Barnawatha, south of Albury and built the Hermitage but much of the property was resumed for smallholdings. Going into politics, he held the Legislative Assembly seat of Murray from October 1859 to May 1862. At a recount after the 1861 election he was disqualified and did not stand again. In the early 1860s he bought Thelangerin on the Lachlan River, near Hay, financed an expedition to the north of Bourke and took up Delalah on the Paroo River. Foreclosed about 1864 he was forced to sell when land values were at their lowest. Near ruin, he took up his brother Robert's offer of land at Moorwatha near Howlong, New South Wales, and farmed there from 1865.
