My in-laws asked if I'd put together a website for them that contains their family tree. As I wanted to be able to build a site that they could update without waiting on me to do the coding, my first thought was to see if there were any WP plugins that generated family trees. After installing and configuring WP Family Tree, I can easily say that this is exactly what I was looking for. It's easy to install and configure, and it's easy for non-technical people to add new family members to the tree. As the plugin hasn't been updated in a while, it does have one issue in terms of its compatibility with WP 3.5.2. When WP Family Tree is active, WP has trouble generating preview images when you add media to a post. Granted, as long as you give your images obvious titles, you should still be able to select the image you want for a given post. That said, it would be great if WP Family Tree could be upgraded to compensate for this issue.
