Using the 1885 Nebraska State Census
The problem was that Tamme's name was written in a nearly impossible way to search for on one of the schedules. Tapping Tamme Tammen discusses how I searched for Tamme in these schedules, some general techniques, and samples of the actual census schedules showing Tamme's entry.
And if anyone is related to Tamme...let me know firstname.lastname@example.org. His older sister Tjode Anna Focken Tammen Goldenstein is my 3rd great-grandmother.
