Nearby Communities in the 1890sWe largely built the following list with information that came from an Atlas published by Rand McNally in 1895.  The Atlas had details such as the population of the community (which appears to have come from the 1890 Census) and whether there was a post office and/or railroad service available.  Over time, we will continue to add communities that we find during our research. If it applies, we indicate whether a community no longer exists and is now historic.<1> The Rand McNally Atlas shows that Castle Hill had a population of 46 people in 1895 with a post office and no railroad service.  In 2020, Castle Hill had a population of 390 people. The following communities are listed based on their distance from Castle Hill, with the one closest to Castle Hill listed first.

Footnotes ...
| <1> | We use the term 'Historic' broadly and it generally means that the community no longer exists.  However, it can also mean that the community might still exist, but was significantly larger or had a more 'official' existence in the past than it does now.  Unfortunately our sources of data have proven to be unreliable.  If you can provide us with more specific information about Castle Hill, please let us know so that we can improve our accuracy. |  | <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> | While we're fans and frequent users of TripAdvisor, you should know that we're also members of the TripAdvisor affiliate program. |  | <4> | An 'estimated' location is one where we have been given GPS coordinates, but are unable to verify the accuracy of those coordinates.  That said, we have some confidence that we have placed the marker near the actual location.  A typical reason for being unable to verify a location is that it might be on private property or maybe historic and gone without an obvious trace. |  |  |
