Footnotes ...

<1>	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 Cornwall refer to themselves. It's important to note that there aren't any rules for taking a city's name and turning it into a demonym. A demonym is informal and while the majority of Cornwall may use one name, keep in mind that others may use something different.
<2>	The elevation is an estimate for the area around Cornwall - it will be higher in some places and lower in others.
<3>	Area code (343) is an overlay for area code (613).
<4>	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.
<5>	While we're fans and frequent users of TripAdvisor, you should know that we're also members of the TripAdvisor affiliate program.
<6>	If we found a location and have questions about the accuracy of our information, we will simply say that the marker is 'in the vicinity'. We are not confident about the location and the position of our marker is only a rough guide. If we have too many doubts about the location, we will not include it in our database.
<7>	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.
