You are missing something very basic, hard to tell what exactly.

First of all, the parent-child relationship between form is effectively make defunct. A form can be a parent of some other control, except a form. You can work around it, but this is pretty much useless.

Instead, there is ownership relation (very important for UI consistency if you use more than one form, always use Form.Owner) and, of course, class inheritance. Inheritance has nothing to do with relationship between instances. In other words, any child controls can be added to any of the forms, under the same name or different names. If just does not matter. If the child control is inherited, this is a separate, hence an independent instance, because its parent form is also a separate instance. If can be of the base class, any form class from the inheritance hierarchy or exact same form class — it just does not matter.

I think your question is based on misunderstanding of classes vs their instances (objects). You need to learn it to understand it very clearly. This is not even the heart of OOP, this is one of the very basic prerequisites to understanding of real OOP.
