How do you add to family tree???

I believe you need someone who has entered more than five bills before you can enter them but????
I believe these would be my hit kids.
Please help

If someone comes to this site for the first time by finding and entering one of your bills…they are your hit kid. If that user continues on the site and enters five or more bills of their own….they are automatically added to your family tree…but not until they have added five bills! You do not have to do anything to the family tree…..it updates automatically.
