JACOBSEN< MARTINSEN FAMILY......Raade, Ostfold

I am searching for any information on the Martinsen family from Raade, Ostfold. I am unable to locate any of them in the 1865 census which is strange, as I can't seem to locate them on any passenger lists out of the country either. I am searching for MARTIN CHRISTIAN JACOBSEN and MAREN ARVESEN parents of JACOB -born Raade 31 Jan 1854- ended up in New Zealand JENS - born Raade 6 Aug 1859 ELINE - born Raade 13 Aug 1861 and am also searching for the children. I would imagine there are more children but don't know their names. MARTIN CHRISTIAN JACOBSEN was also born in Raade, Ostfold, on 13 Jan 1815. His wife MAREN ARVESEN I have no information on. MARTIN CHRISTIAN JACOBSEN'S parents were JACOB JOHANSEN, born about 1780 (Raade),and died 21 March 1853and INGEBOR KNUDSEN born 1782 and died 1860. I would appreciate any suggestions as where to look for the family. Thanks, Kymm
