Gramps

Their explanation
GRAMPS is a software package designed for genealogical research. Although similar to other genealogical programs, GRAMPS offers some unique and powerful features, which we'll discuss below.

GRAMPS is an Open Source Software package, which means you are free to make copies and distribute it to anyone you like. It's developed and maintained by a worldwide team of volunteers whose goal is to make GRAMPS powerful, yet easy to use.

Our explanation
If you are related to the genealogy field, you probably have used the software Family Tree Maker (for Windows) at office or at home. Gramps could be a nice replacement for Family Tree Maker in Linux.
