Elin Helstrom

Looking for Elin Jonsdotter Pettersson Helstrom.She married Elias Pettersson in Sweden. They emigrated to Minnesota in 1954 with children Johan, Johanna, and Matilda. Elias died in passage and Elin married Charles/Carl Helstrom. They had 3 children including Emma, my ggrandma.Elin left Charles/Carl in 1867, taking Johan, Johanna, and Matilda with her. She is in the Chisago County, Minn. census in 1870. Reportedly she went west of Minneapolis to start a tree farm. At some time Emma took my grandma, Lottie (Charlotte), b 1884, to visit Elin somewhere near Olivia or Litchfield. I cannot find Elin in any of the records in Meeker, or Renville counties.Any infor would be appreciated.
