The 1880 Ransom County, North Dakota, Census contains 17 pages (census
images) in Enumeration District 57.
Page 57-15 is not included, because it is LaMoure County.

The name of each image file is the page number. (In the case of 1880, 1900,
1910,
and 1920 census, the file name includes both the Enumeration District and the
page number.)
