# Family Groups

A Family Group is the container for a set of family tree data and mirrors the GEDCOM 'FAM' tag. It is one of the core records in the file used to define a family unit, linking individuals together as husbands, wives, and children to create your family tree's structure.

## Creating a Family Group

Family Groups are mostly created automatically when you connect a child to a parent or vice-versa.

They will be within a lineage and can be thought of as generational 'nuclear' or 'sub' families with the larger family lineage.

## Finding a Family Group ID

The ID is shown in the **ID column** of the Family Groups list. If you cannot see the ID column, hover over the group name and click **Edit** - the ID appears in the browser's URL bar as `tag_ID=X`.

## Editing and deleting Family Groups

Delete a Family Group using the option in the Actions coloumn on the right.

## Assigning members to a Family Group

When adding or editing a member, the **Family Group** taxonomy box appears as the 'Family Relationships' block towards the bottom of the screen. A member can belong to more than one Family Group if needed - useful for people who appear in multiple family lines.
