My Family Health Portrait – part of the US Surgeon Generals “Family History Initiative”
Requires: Windows 98+, NT+, 2000+
Basically, this is geared towards medical genealogy – it is a simple program that you can use to track the medical history of your family. The site mentions diseases you should be concerned about. You can store this information in your normal genealogy application, but it is included here since some may find it useful (and it is easier to use to track medical history).
