Poseidon

I Started with family oral history that my Great Grandfather came from Norway, jumped ship in South Australia and changed his name from Olson/Olsen to Wilson. It is also believed that he was accompanied by another person when he jumped ship. To cut the story short, Australian records that match closest indicate a Thomas Olversen 18 Ordinary Seaman along with Ingrebert Ingrebesson 23 AB and Christopher Christopherson 28 AB jumped ship on 16-3-1874. The latter two were arrested and finded and departed with the ship. The ship was the Poseidon. A Norwegian barque cargo ship with the master named Ellisen and owned by or agent J Webster and Co. Its journey was Norway, London (departed 5 Nov 1873) , Adelaide,(Arrived Feb 1874) London. It carried fire bricks, wire, pig iron, coal, batterns, floor boards and stout and returned with 6698 bags of wheat. How can I track down information on this ship or its owners?
