Who are the parents of Bergitte Aanensen

I know a lot about the life in America of Bertha Olsen after she married Martin Olsen. But I do not know the names of her parents. She came to America as Bergitte Aanensen. She arrived on 17 June 1898 in New York on the Thingvalla. She left Norway on June 3 1898 and is found as #31255 in the list of Emigranter fra Kristiansand. Found here Bergitte I have searched through the Church books for Arendal for 1876,1877 and 1878 as well as the Church books for Åmli, Aust-Agder. She is thought to be a cousin of my Grandfather and he is found in the Åmli, Tovdal scanned church book. Any information on the parents of Bergitte Aanensen would be appreciated.
