I am looking for information about my gggrandfather and his family. His name is Christian Olson or Olson-Ronning and I know they lived in the Lacrosse Valley area. His wife's name was Ambjo . My great grandmother, their daughter ' was born in Lacrosse Valley, west Salem WI on October 15, 1860. She also had a sister ella and a brotherNels that I know of. They moved to Valley City, ND area in 1882. He may have been a minister at some time in his life. Can anyone help me? Thanks so much.
