GRAMPS is a free professional Genealogy software program to create efficient family trees. GRAMPS is an acronym for Genealogical Research and Analysis Management Programming System & the software works on Linux, Windows, OSX, BSD, and Solaris, but the Linux versions are generally the most up-to-date.
GRAMPS is a feature-packed free genealogy application. Most popular genealogy software tracks records in the GEDCOM format. GRAMPS can work directly with the GEDCOM even though it has its own format available. This makes it easy to import your old genealogy tracks into GRAMPS & update them very easily.
