You can use family groups to define which members will appear in a family tree. Multiple Groups are available in the Premium versioin of the plugin.
You do not have to use these Groups to define a particular family or name them after an individual family – for example, you might just want to display one line or a few generations of a lineage in a family tree and you could create a Group called ‘Tree01’ or ‘Johns Children’ to display this set of people in their own tree.
