Gramps (Genealogical Research and Analysis Management Programming System)
Gramps is a free genealogy software project and community. We strive to produce a genealogy program that is both intuitive for hobbyists and feature-complete for professional genealogists. It is a community project, created, developed and governed by genealogists. It is available for Microsoft-Windows (32bit & 64bit), Mac OS X, BSD, Solaris, Linux as well as a Linux Live CD that you can try out without installation.
