As trees can get very large and unwieldy, we recommend creating smaller, more focussed, trees if you don’t need to display everyone in one tree or if you want to create more in-depth pages with informations on specific branches of the tree.

By adding some family members to specific ‘Family Groups’ (see here) and using the shortcode ‘Root’ person option (See Here) you can control which people appear in a tree display.
