Ovidia Bernhardine Clausen

We are looking for information on the wife of a relative of my husband's. Her name was Ovidia Bernhardine Clausen (7 April 1844-1915), and she was probably the daughter of a minister or government official, living in Bærum before her marriage. We presume that her father's name was Clausen, since the masculine form is used in regard to her, rather than the feminine patronym. However, some family members think that her father was Bernt Olsen (born 10 June 1814), and they therefore assume that her last name was Olsen. We are fairly certain that her mother was Anna Torgerson Holm, born 21 January 1810. Ovidia married Kittel Kittelsen Helland (1822-1909) from Helland in Sand, Rogaland. He decided to become a minister, sold his farm to his sister, studied theology, and was sent to Wiota, Wisconsin. After some years he returned to Norway and served as minister at churches in Kongsvinger and Sola (Håland). The couple were married ca. 1867 and had nine children. We would appreciate any information about Ovidia's parents and family!
