I just wanted to say thank you for your hard work! It is appreciated.

This extension on Microsoft Edge browser is changing the way I work. I am solving mysteries, eliminating confusion, and de-duplicating places, plantations, farms, ambiguous names, and non-populated areas more than ever before and with MUCH less effort. As you state, the data is already out there, but your website and extensions make it much easier to access and use, more than any process or tool that I’ve ever tried. For decades, I’ve avoided fixing these places and now I’m tackling it head-on.

As I librarian I wholeheartedly support this Chrome extension! We have installed it on all of our genealogy computers at the library because it works for AncestryLibrary Edition too! So easy to use and is extremely helpful when searching older records. Once you've identified an accurate place name for a specific time period you will then be able to search other databases with that same location to open up much more information in your research.
