thor olsen, kragerø policeman 1865 census

Kragerø connections: Thor Olsen, Policeman, 1865 census I am descended from Thor Olsen who was a policeman in Kragerø. I have found him in the 1865 census, and also a reference to his daughter Kirsten marrying a Swede Levin Olander and emigrating to Wisconsin in 1881 with children Victor Oluffa and Ivar. Thor's first wife was Helene, and he probably married second wife Severine around 1862. Children of Thor and Helene: Kirsten b 1851, Iver b 1854, Ole, b 1857, Neils Peter b 1859, Alberth M. b 1861. Child of Thor and Severine, Thora S. born 1863. I am descended from Niels Peter Olsen, a sailor who eventually married and settled in Liverpool UK. I am seeking both earlier family history and links to other branches of the family in Norway and the US. Also advice on best way to access church records for Kragerø for 1800 onwards. (I can only find data for Swedish immigrants to Kragerø on line at www.disnorge.no)
