Ancestors
Build your family tree or synchronise with familysearch.org
Ancestors is a family tree builder and viewer.
You can build your family tree within the application, or you can use the built-in browser to log in to familysearch.org, build your family tree there, and then synchronise your local copy of your family tree with the web site data.
The tree can be exported as an image, a PDF report including a timeline for each person in the tree or a GEDCOM format file.
This application is free to download. A Linux version is currently not available due to technical constraints.
