] What do you think of this list? Especially the Mrs. Tilney item?

How about this? The three mothers reflect the roles we need our mothers to play as we are growing up.

Mrs. Morland is the ideal mother for a young girl; kind and protective, the perfect balance between love and practicality. But when we become teenagers, parents need to back off a bit and let us learn for ourselves. Granted, Mrs. Allen does this through absent-mindedness, not intention, but the result for Catherine is the same.

For the third...well, if you're lucky, your parents can become friends you can rely on to have your best interests at heart. Older and more experienced than you, someone you can turn to for advice but who respect the fact that you're grown up now. So I would say Catherine's third "mother figure" was Eleanor Tilney.
