Background
He was born the only son of Joseph Gilbert (1800–1881) of Pewsey Vale near Lyndoch and his wife Anna née Browne (1812–1873).
He was born the only son of Joseph Gilbert (1800–1881) of Pewsey Vale near Lyndoch and his wife Anna née Browne (1812–1873).
He was educated at Saint Peter"s College, and in 1864 enrolled with Cambridge University.
In 1872 he helped Ted Bagot (1848 – 1881) and his foster-brother James Churchill-Smith (1851–1922) drove 1,000 head of cattle from Adelaide to the MacDonnell Ranges where he had acquired three leases centred on Owen Springs Station and Edward Meade Bagot another two, on Emily Gap and Undoolya Stations. This was recognised as one of the great droving feats of Australian pastoral history. He took up management of Owen Springs station in 1873 and in 1875 was managing of all his father"s properties.
When his father died he disposed of Owen Springs, the freehold of 32,000 acres at Mount Bryan, and the Oriecowe run on Yorke Peninsula in order to concentrate on stock improvement at Pewsey Vale.
lieutenant was not long before his wool was fetching record prices. He had considerable success with wines also, though according to one source, he treated winemaking more as a hobby than a business.
Having increased output in one year to 17,000 imperial gallons (77,000 l) this would rank as a very serious hobby. William junior sold Pewsey Vale shortly after inheriting it to pay probate duties.
He was appointed to the board of governors of Saint Peter"s College in 1894.
He was appointed a founding director of Bagot Shakes & Lewis formed by amalgamation of East. M. Bagot & Company and Shakes & Lewis in 1888. Their 11 children included:

Thomas (12 September 1889 – 1 May 1938)
