House Norrey is the formal name of the Norreys, a mountain clan dwelling in the high peaks north of the wolfswood, nearer the Nightfort and the Gift than any other clan and long friendly with the Night's Watch; some even whisper that the Night's King himself was born a Norrey. Lady Arra Norrey wed Lord Cregan Stark and bore him Rickon Stark, and the clan rode with Cregan to hunt down Sylas the Grim's free folk raiders.
Norrey men answering Robb Stark's call are caught on the wrong bank of the Trident and cut down by Gregor Clegane's riders, and young Owen Norrey falls to crossbow bolts at the Red Wedding. When Stannis Baratheon marches north, Lord Brandon Norrey, called the Norrey, brings the clan to his cause; Brandon rides to Castle Black to treat with Jon Snow, while his son Brandon the Younger joins the king's advance on Winterfell.
