Channing, Tannings, Tanningues, Thaninges, Thaningues, Thanningues, Tingues, Tranurgor
By the name, this would seem to be another “Gore” dukedom, with Brandeban (Brandelis) as its duke, a friend of Sir Sagramore.
Taningues was the home of one of Arthur’s knights, Sir Alier. Additionally, a squire who was knighted by Gawain, Helain de Taningues, held a castle in the vicinity of Taningues. If Taningues is identified as the peninsula at the western end of Sussex, then the castle might be Chichester (Roman name Noviomagu).
