[2] Thesu ‘the Tees’: A river in northern England. The initial <Th> spelling in most mss is curious (and not matched in English sources), and is possibly attributable to Latin influence (see Townend 1998, 85). A battle by the Tees is not mentioned in the ASC (s.a. 1016), though it is plausible (see Poole 1987, 273).
