What I really need to do is determine who might have been there in 1885 as that is the year of the bulk of the records in Ancestry.com's database. The "Source Information" from the Ancestry.com site is:
- Nebraska. Cass County. “County Census, 1876-1882.” Microfilm RG220, 9 rolls. Nebraska State Historical Society, Lincoln.
- Nebraska. Lancaster County. “County Census, 1860-1880.” Microfilm RG207, 4 rolls. Nebraska State Historical Society, Lincoln.
- Schedules of the Nebraska State Census of 1885. NARA Microfilm Publication M352, 56 rolls. Washington, D.C.: National Archives and Records Administration
Always read the description before searching any online database.
