Burial of Birgitte Muus married Lorentz Klüver

Looking for burial place in Norway for Birgitte, her husband, and their 2 sons J.W. and Bernt Klüver. Birgitte was back and forth between Norway and USA. But I believe she died in Norway in August 1935. Birgitte's father was Rev. Bernt Julius Muus, founder of St. Olaf College. Thanks much, Kay
