  • Of Special Interest ...
    • The GenDisasters website specializes in newspaper articles about tragedies and disasters. While it makes interesting reading all by itself, it should be of special interest to genealogists and family historians looking for people who were either affected by or directly involved in such tragedies.
    • At this time (Dec 2022), GenDisasters website is currently offline due to a hacker attack. Hopefully they will be back soon.

Footnotes ...

<1>On a yearly basis, the US Census Bureau creates an estimate of the county's population. Keep in mind that this is an estimate and not an actual count. The last physical count was the 2010 Census and the next count will be for the 2020 Census.
<2>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.
<3>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.
