Andrew Tennant (1835–1913) was the son of a Scottish shepherd who had come to South Australia as an assisted migrant in 1839 and established ‘Tallala’ station near Port Lincoln. On the death of his father, Tennant took over ‘Tallala’ and acquired a number of properties on Eyre Peninsula and in the Far North, some in partnership with his brother-in-law, John Love. He had large interests in several mining companies and was a director of the Adelaide Steamship Co., the Commercial Bank of South Australia and the China Traders Co. Tennant sat in the House of Assembly (1898–1902) and Legislative Council; he bred and raced horses and was a Freemason. In 1862 he married Rachael Christina Ferguson; his children consolidated the family’s position through marriage into the gentry families of South Australia.
