Footnotes ...

<1>	If you're interested in how the shape of Michigan's counties, including Lenawee, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>	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.
<3>	The elevation is an estimate for the area around Seneca - it will be higher in some places and lower in others.
<4>	ZIP Codes have been created by the United States Postal Service (USPS) as a way of grouping addresses to make delivery more efficient. The boundaries of the ZIP Code can be changed, re-assigned, eliminated or overlapped with other ZIP Codes. So keep in mind that any given ZIP Code is only 'loosely' associated with a community (such as Seneca). When looking for a ZIP Code, whether Seneca or elsewhere, it's always best to check the website of the United States Postal Service (USPS).

<6>	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.
