Now, say 2 of the classes also share some attributes but the third one does not, should I I place these attributes in each child class or place them in the parent class?

Obviously, placing them in the child classes will mean duplication of the varaibles, properties and any methods which act on these properties. But putting them in the parent class will mean that the third class, which does not require these attributes, will have access to them. Is this a problem?

class A
class B inherits from A
class C inherits from B
class C1 inherits from C
class C2 inherits from C
