Please note that if the node/box is white (with a blue outline) this is based on the perspective from which you are viewing the Tree. For instance, if you click on the 'tree' link, the small tree icon (both from the node/box itself) or used the 'View Tree' button on their Profile page, you are viewing the Tree with that person as the focus node. Therefore, the node will appear white.
For example, George Washington's node is white because you are viewing the tree from his perspective.
