Footnotes ...

<1>It's a common practice for mapmakers to remove the apostrophe from possessive names. So Lefferts Mill may originally have been Leffert's Mill. Sometimes the trailing 's' might be dropped altogether, in which case Lefferts Mill might be written as Leffert Mill. For more information, please visit our Genealogy Helper Page for Lefferts Mill.
<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.
