Brigham City Museum of Art & History – Northern Utah’s culture hub can help connect you to photographs, documents, and other resources to aid in research into topics related to the history of Box Elder County. (The museum is the de facto historical society for the county.)
Brigham City Museum online collections – Access many of the items in the collection fo the museum without having to leave your house! Start searches broadly and narrow as needed. Be sure to search alternate name spellings (Jensen, Jenson, Jansen, Janson, etc.) as many early Brigham City families used multiple spellings (and sometimes typos exist too!).
