Lorenz (Lars) Ellingsen MARINER

Hi from Oz. Searching for details of my Grt Grt Grandfather ( my mother was an Ellingsen) who left his ship in Melbourne or Geelong in the early 1850s to try his luck in the goldfields. I have all the details re his marriage (to Katharina Haub) and his children once in Australia. I also have traced his parents TO kRAGERO in Norway (Elling Knudsen and Ane Frederikdatter). I would like any imformation on his siblings and from what port and on what ship he left Norway? Any assistance would be gratefully accepted. BRIAN MCLEAN.
