GRAMPS

GRAMPS is an open genealogy software product.

Allows you to use your computer to store, edit and explore genealogical data.
GRAMPS attempts to offer all the features common in other available genealogy programs. However, it provides additional integration options that are not common with these programs. This is the ability to insert any piece of information directly into GRAMPS and rearrange/manipulate individual/all events throughout the database. This assists the researcher in research, analysis and correlations with the potential to fill in gaps in relationships between subjects.
