Union Veterans Schedules
Although the Dakotas fell under Minnesota Territory for the 1850 federal census, the only whites enumerated actually lived in that territory’s Pembina County, now North Dakota. Only the schedule for Jefferson Township of Union County remains of the 1890 population census. Microfilmed copies of all federal censuses listed above are available in the South Dakota State Historical Society (see Archives, Libraries, and Societies) and are available from them on interlibrary loan. The 1880 and 1900 Soundexes do not circulate. The mortality schedules are available on microfilm and also have been indexed by AISI (see page 3). These are available at the South Dakota State Historical Society in Pierre, as well as various other repositories. The Sioux Falls Public Library, 201 North Main Ave., Sioux Falls, SD 57102, has microfilm copies of the 1860, 1870, and 1880 federal population schedules for the territory, as well as for the state. The 1890 census (as with other states) was destroyed by fire. School censuses by some counties are in state archives.
