I know the name of an object - how do I get the name of the object that contains it?

Question

If I have a Movieclip, I can trace the name of the Movieclip
that contains it using the _parent property.
With a generic object, is there a way to trace the name of
the object that contains it?
Please, please tell me - this will be a huge help.
Thanks

Thanks for these comments - my problem isn't with MovieClips.
I need to know if there is something which is the generic Objects
equivalent to the MovieClips _parent property.
Here's some code that hopefully will help explain further:
class MyClass extends Object {
var myObject:Object;
function MyClass (){
myFirstObject = new Object();
myFirstObject.theParent = this;
private function getNameOfParent(p_object:Object){
// Some code to return the name of the object that contains
p_object
trace(p_object.__proto__); // Output: [object Object]
trace(p_object._parent); // Output: undefined
trace(p_object.theParent); // Output: [object Object]
return ???
public function doSomething(p_num:Number){
var parentName = getNameOfParent(myObject);
// do some more action...
Timeline code:
var myClass1 = new MyClass();
myClass1.doSomething();
