An obituary of 1884 states that James Brock arrived in Tasmania in 1833. It appears that James's sister Marion (1799-1883) was also in Tasmania, marrying a George Wilson in Hobart in 1832, and settling near Oatlands. James, a farmer and councillor in the Green Ponds municipality, was associated with land in the Oatlands area including Campania (Belmont) and Richmond (Belgrove). James married Isabella Angus Miller in 1847. They had three sons and six daughters: Henry James (Jim) (1848-1898), William (1851-1913), Janet Campbell (Daisy) (b.1852), Alexander (b.1855), Margaret (b.1856), Marion (1859-1892), Kate Kennedy (1865), Jane Wilson (1868-1908), and Flora Isabella (1871-1956). Alexander settled in Victoria. Jane Wilson and Kate Kennedy moved to New Zealand. William was an MHA for Richmond from 1882 to 1885, before also moving to New Zealand in 1909. Henry James, initially a merchant in Hobart, settled in Parattah, Oatlands. Henry married Georgina Agnes Mercer (1863-1899), and together they had seven children - James (b.1882); Henry Eric (1884-1963); Janet Isabel (1885-1897); Harold James (1887-1941), Claudius Alexander (Claude) (b.1888); Kathleen Winifred (b.1890); and Lorna Doris (Muriel) (1891-1980). Henry successfully invested in the New Golden Gate Gold Mining Company at Mathinna. Utilising his wealth he built Lawrenny House in 1892, and purchased the larger 'Lawrenny' property (NG315) in 1896. Henry passed away in 1898, and Georgina in 1899. Claude, Eric and Harold Brock established the company Brock Bros. Pty Ltd, purchasing Lawrenny from their father's estate. Together they enhanced the irrigation system and productivity of the property. The Lawrenny property stayed in the hands of the Brock family until the 1940s, when it was purchased by the Government as part of the Solider Settlement Scheme. Brock Bros. was also involved in the Tasmanian horse racing industry. Lorna Doris (Muriel) Brock married Launceston born horse trainer George Henry Cann (1893-1979) at Glenorchy in 1922. Doris and George lived at Rosetta and New Town. Doris passed away in 1980 aged 88.
