Hmm, don't even know where to begin with 1002 - since they're all major characters in the same book... might need a hint or two!
For 1001, don't know, but since you mention wives I'll post some info to start us thinking...
Frank and his wife Helen were both taken from this world to Narnia, where they became king and queen. They had several children including at least two sons, I think.
Caspian VIII - don't know about his wife, but they were the parents of Caspian IX and Miraz.
Lune's wife died when the children were young, but they had twin boys, Cor and Corin.
Mr and Mrs Pevensie had four children, including two sons, Peter and Edmund.
So they all had at least two sons, but we don't know the names of Frank & Helen's sons. Could they be the odd ones out for that reason?
It's also the case that Mr & Mrs Pevensie were the only ones never to be king and queen, but is that too obvious an answer?
