The Sorcerors Stronghold in Sherwood Forest

Ekwall's The Concise Oxford Dictionary of English Place Names p 464, features Teversham just east of Cambridge and Teversal on the western fringe of the ancient extent of Sherwood Forest in Nottinghamshire. Teversham was Teuresham  in 1086 which appears to be from Old English *tiefrere or sorceror. Lying so close to the university of Cambridge, when Oxford had a formidable magical reputation, may not be coincidence. It is also curious that it lies just south of the village of Stow cum Quy, because Stow is a common place name associated with holy places.
Teversal was Tevreshalt and Tevershald in 1086 where Anglo-Saxon 'hald' means refuge or stronghold. Caitlin Green discusses these two place names in her blogs, but I would add to her comments that if, as seems likely, this place on the fringe of the ancient forest of Sherwood, means Sorceror's Stronghold, then it may not be isolated by way of a magical name. Just to the south is Huthwaite which was Hodweit in 1199. A.D. Mills A Dictionary of British Place Names suggests this is from Old English hoh, headland or spur of land with thwaite meaning clearing. This may be so, but it is not conclusive by any means. It is equally possible that thwaite, as an Anglicised suffix, is preceded by hod or perhaps hud in British. If it is hud or hut, as is suggested by the later spelling of the name, then it means magic. Hod can be a variant on hood as in Robin Hood, which would be very appropriate for Sherwood Forest. Just as Woden was known as Grimr, the hooded or masked one, Jacob Grimm pointed out that the Welsh magician Gwydion and Woden the magician were cognate. Magic, by its very nature has to be kept hidden from the uninitiated These various strands all point to a Mercurial magical background which might lie behind the name.
Huthwaite is confusedly associated with Hucknall which may have some sort of connection. The village has Herrod's Hill to the north which has the place name Whiteborough adjacent to it, suggesting an ancient earthworks was once sited there. If this was an area in Sherwood Forest with a magical clearing and a sorceror's stronghold, it may reflect far more ancient origins to the Robin Hood legend in this area, especially because Bronze Age burial mounds in Somerset and elsewhere, are ascribed to Robin Hood while there are many ancient earthworks with Woden's name, such as Grims Ditches.
