Looking for info. on the NILSEN Family from Lenvik

I am trying to find more info. on the NILSEN Family (the last name could have been spelled NILSSEN). Nils Benjamin NILSEN, and his Wife Sophie (Sofie) Andrea (Andersen) NILSEN. I believe that they had four Children together. Nils was born in Dyroy, Norway on July 9, 1836. Sophie was born in Lenvik on June 6, 1841. They were married in Lenvik on Aug. 6, 1862. I would like to know more about Nils' Parents, and Sophie's Parents if possible. Thank you for your help.
