(1819–72), born Scotland, migrated to NSW in 1836. He soon became well versed in bushcraft and made money by trading in squatting leases, taking up a number of stations west of the Darling 1850–60. In August 1861 he was chosen to lead the SA Burke Relief Expedition, after the explorers Burke and Wills failed to return. His subsequent journey of exploration towards the Gulf of Carpentaria, the second to cross the continent from south to north, was recorded in his McKinlay's Journal of Exploration in the Interior of Australia (1862). In 1865 he made further explorations in the Northern Territory before settling down as a pastoralist near Gawler.
