North-west of Canterbury there is a village called Faversham. Saxon-fixated etimologists originally understood this as "Feofar's Home", Feofar being some sort of AS name. However, archaeology has shown that the village was dedicated, from before Roman times continuously until well into the English Dark Ages, to iron-smithing. As I imagine you know, the smith was faber in Latin, and Faversham was obviously "The home of the smiths". (Industrial sites in Roman times were normally outside town areas, because of the smelly and dangerous nature of such things as leather making and the heavy use of fire in kilns, smithies and so on.) This place would surely be bad news for fairies, since English tradition insists that iron drives them away. You could imagine Faversham as a kind of faerie Hell or Mordor.
