join-fu

Considering below tables and relationships:

parent --1:Many-- children --1:Many-- shubchildren

Parent may or many not have children records.
children always have subchildren records.

I wan to write a qiery to select parent names where any if matched parent.name,children.name or subchildren.name

Here i understand I have to do a left outer join between parent and children. But what kind of join should I put between children and subchildren ?
