Footnotes ...
| <1> | If you're interested in how the shape of Wisconsin's counties, including Winnebago, have changed over time, we recommend the Atlas of Historical County Boundaries. |
| <2> | The location has been supplied by the Geographic Names Information System - which is maintained by the U.S. Geological Survey (USGS). While these values should be definitive, we found that accuracy can vary and you should double-check the location if accuracy is required. |
| <3> | A demonym is the name for a resident of a community which is usually derived from (or is related to) the name of that community. In other words, it's how the residents of Eureka refer to themselves. It's important to note that there aren't any rules for taking a community's name and turning it into a demonym. A demonym is informal and while the majority of Eureka may use one name, keep in mind that others may use something different. |
