Magritte descriptions in hierarchies of classes

Suppose I have a hierarchy like this:

Object subclass: #ClassA
	instanceVariableNames: 'name'
	classVariableNames: ''
	poolDictionaries: ''
	category: 'Example'

ClassA subclass: #ClassB
	instanceVariableNames: 'bInstVar'
	classVariableNames: ''
	poolDictionaries: ''
	category: 'Example'

ClassB subclass: #ClassC1
	instanceVariableNames: 'c1InstVar'
	classVariableNames: ''
	poolDictionaries: ''
	category: 'Example'

ClassB subclass: #ClassC2
	instanceVariableNames: 'c2InstVar'
	classVariableNames: ''
	poolDictionaries: ''
	category: 'Azteca-Model'

ClassA is just an abstract parent with the common functionality for the 
other classes. Same for ClassB.
Only objects from ClassC1 and ClassC2 are to be created.

Should I create a "descriptionName" method in the class side of ClassA 
to be inherited for ClassC1 and ClassC2 or should I create a 
"descriptionName" once for each of ClassC1, ClassC2.
The same question about the inst vars for ClassB.

Summary, when you have a previously created hierarchy of classes and you 
are trying to refactor code (deleting duplicated code and replace it 
with magritte) how should you proceed?

It is valid to inherit the descriptions of parent classes?

What if for ClassC1 name should be displayed as 'Name' and for ClassC2 
should be displayed 'Title'?
