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:
| Tag | URL | Description |
|---|---|---|
| FSWIKI | https://www.familysearch.org/learn/wiki/en/ | Family Search Wiki |
| NAHCB | https://publications.newberry.org/ahcbp/ | Newberry Atlas of Historical County Boundaries (US) |
| WIKI | http://en.wikipedia.org/wiki | Wikipedia |
| http://maps.familysearch.org | 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.
