Vilhelm Moberg and The Emigrants and A New Land One topic/thing that I think would be worth considering are the novels written by Vilhelm Moberg based upon the immigration of Swedes to Minnesota. These novels recently reprinted by MHS Press, e.g. The Emigrants, The New Land, etc., were brilliantly brought to the screen in two films by Jan Troell and starring Liv Ullmann and Max von Sydow. Moberg himself was greatly influenced by the detailed diaries of Swedish immigrant Andrew Peterson, who came to the Scandia area. I think that this combination of history, literature and film brought about a resurgence of interest both here and in Sweden at least in the 19th- and early 20th-century immigration. It may well have had as great an impact as Alex Haley's Roots in encouraging people to search out their roots and extended relatives.
Given the lasting impact of Scandinavian immigration upon this state, I could see these as something important for your consideration.
