Research tip

Minnesota took its own census in 1865, 1875, 1885, 1895 and 1905. They are indexed in the Historical Society's People Records Search (not every county appears in every year), and the 1905 census, like the 1895 census for men over 21, says how long each person had lived in the state and in the district, a clue to when a family arrived.
