Hovding 1873 to New Zealand

Hi, I wonder if you may be able to help me. I have been searching for Karen and Antons Amundsen's parents on the 1865 census and have not been able to find them, or Anton and Karen either. I dont know if I am doing something wrong or not. If someone could please help me to find out more information, I would be so grateful, their details are as follows: Anton Emil Amundsen - Born 16 May 1850 in Naes, Akershus Christened 16 June 1850 in Ullensaker, Akershus His father: Amund Jensen His mother: Kari Amundsdatter Married Karen Helene Hansdatter on 6 February 1873 in Trefoldighet Menighet, Akershus Karen Helene Amundsen born 1845 Christened 13 July 1845 in Krakstad, Akershus Karen's father: Hans Holmsen Karen's mother: Elen Johannesdatter I would especially like to find out Karen and Anton's brothers and sisters names and the name of their farm if they had one. Also dates of birth and death for the parents. Please if these names ring a bell or if anyone can help me to find out more about the family further back it would be so wonderful. Thank you so very much for all your help, Astrid Cayless
