Gramps is a free genealogy program. The Gramps name stands for Genealogical Research and Analysis Management Programming System.
Gramps helps you track your family tree. It allows you to store, edit, and research genealogical data. Gramps attempts to provide all of the common capabilities of other genealogical programs, but, more importantly, to provide an additional capability of integration not common to these programs. This is the ability to input any bits and pieces of information directly into Gramps and rearrange/manipulate any/all data events in the entire database (in any order or sequence) to assist the user in doing research, analysis and correlation with the potential of filling relationship gaps.
Gramps is programmed in the Python language.
Gramps currently runs on Linux, Microsoft Windows, Apple MacOS, Solaris, BSD, other UNIX-like systems.
