According to the Bureau County Republican and the NewsTribune (Illinois Valley), popular Danish actress Suzanne Bjerrehuus was in the area filming stories of her great-great-grandparents, who emigrated from Denmark to the American Midwest in 1869. (They apparently left behind one of their six children, from whom Bjerrehuus descends.)
As part of her whirlwind family history tour, Bjerrehuus reportedly visited the Danish Immigrant Museum in Elk Horn, Iowa. If you have Danish roots, you should probably check out their website. They have a Family History & Genealogy Center, which specializes in helping people find links to their Danish immigrant past. They provide research and translation services and they’ve helped people connect with long-lost relatives in both Denmark and the United States.
