How to add and manage the family members in Google?

When you join a family group, you can share family services across Google with up to 5 family members. The 5 family member limit includes family members who have been invited to join your family, even if they haven’t accepted their invite yet. Your family manager must set up a family payment method before you can use it for purchases on Google Play.
To add and manage the family members in Google, please refer to the following steps:
1. Open [Settings];
2. Go to [Google];
3. Select [All services];
4. Tap [Family group];
5. Tap [Send invitations], and type a name or email to invite your family members;
6. Tap [Delete family group], and enter your password to delete the family group.
