I am looking for any information on Marcus Peter Christensen(son)--my gggrandfather. All I have so far is he had at least one daughter born in Racine, Racine county, Wis. My ggrandmother Lucy Marie was born 1880. Marcus was married to a woman named Nielsine. Later the family (when unknown) moved to Iowa where Lucy married James Frederick Anderson in 1905. From there the Andersons went to South Dakota and other places.
