I hope I’m wrong and someone can point me in the right direction. ADO.NET will handle cascading keys and I know I can write all the code to accomplish this but I would like to maximize the MM biz objects.

Are you storing the primary key of the parent into the child records? If so, you can register one business object as the child of another business object, and set the ForeignParentKeyField property of the child to the corresponding parent object's primary key field. When you do this, the PopulateForeignParentKeyField() method is automatically called when the child records are saved.
