join

I have the following tables/columns:

Parent:
  ParentID

Child:
  ChildID
  ParentID

SubChild:
  SubChildID
  ChildID
  Date

Parent has 1 to Many relationship with Child

Child has 1 to Many relationship with SubChild

For every Parent, I need to get the SubChild with the most recent Date value. How can I do this using SQL. I've tried using MAX(Date), but I can't seem to figure out how to join Parent and Child successfully.

The ideal result set would contain all the Parents joined with all the SubChild columns of the latest record.

Note: using MS SQL 2005+
