Torwynd, known as Torwynd the Tame, is a son of Tormund.
A Storm of Swords
A Dance with Dragons
Tormund reveals to Jon Snow, the Lord Commander of the Night's Watch, that Torwynd died a few days after the battle beneath the Wall from the cold and rose as a wight, after which Tormund had to slay him.
And Torwynd ... it was the cold claimed him. Always sickly, that one. He just up and died one night. The worst o' it, before we ever knew he'd died he rose pale with them blue eyes. Had to see to him m'self. That was hard, Jon. He wasn't much of a man, truth be told, but he'd been me little boy once, and I loved him.
