A Question

This is about the Starks, mainly about Ned Stark ad his family.

I dislike Catelyn Tully, while cutting her off is not great I idea since we do need Robb, Sansa, Bran and Arya.

Also my plan was to let Ned marry Catelyn, but Catelyn pulls a idiotic stunt with Valar and is sent back to Riverlands.That was the idea, but now not sure about it.
