RootsMagic 5 introduced a new feature that checks what you have entered in the Place of a fact/event against a database of counties stored in the file CountyCheckDB.dat. This file is partially human readable when opened in a text editor. What it reveals is that there are four Internet sites that it is set to call for maps and other information:
|Family Search Wiki
|Newberry Atlas of Historical County Boundaries (US)
|England Jurisdictions 1851
The first three appear to get parameters for a specific place that are appended to the URL and passed to the CountyCheck controls “Online Info” and “Online Map” to open these sites on a specific page. The last one is called without parameters for places in England.
