How do you hold on to England if you play as Norway? Destroy the title and then fight many internal wars or what?
What exactly seems to be your problem? Destroying the title might be a good idea in the long run, but in short time, everybody who is a de jure vassal of England will get angry. Your problem seems to be short term, since long term, you really shouldn't have any problems holding onto England, thus destroying the title might not be the best course of action.
I'm not very good as this game as I've mostly played EU. But theres always so many hostile factions/rebellions etc.
you could simply conquer every top holding in all of England before you make peace, this way all those lands will be yours to distribute once the war is over. No dealing with annoying Anglo-Saxon lords this way.
