Hello, Bill Harshaw
Welcome to Microsoft Community.
Windows uses Bing Maps as the location data source. It's possible that Bing Maps has not updated its data yet, or your location is not registered or verified by the data suppliers that Bing Maps uses, such as Navteq, USGS, or GNIS. You can use the Map’s Feedback feature to report the location error to Bing Maps, and provide as much detail as possible, such as your address, postcode, coordinates, and screenshots:
You can also contact the data suppliers that Bing Maps uses, such as Navteq, USGS, or GNIS, and request them to correct the location data for your area. You will find the list of data suppliers and their contact information at Bing Data Suppliers: About Bing and Microsoft News data suppliers (bingexplore.azurewebsites.net)
