Simeon of Durham says the battle was fought near Weondune, or _Ethrunanwerch_, or Brunnan byrge. I have never seen any attempt to identify this Ethrunanwerch with any modern locality in any part of the country. There is no such name to be found now, nor anything suggestive of it, in a gazetteer of England and Wales, and I therefore presume that it has either entirely disappeared or become so altered as to be unrecognizable. Consequently, if I fail in an attempt to identify it, not much injury will result therefrom. The termination _werch_ presents no difficulty. It is evidently _worth_, as in Saddleworth, Shuttleworth, etc., and could easily give place to some other suffix indicating residence or occupation, or even locality. The prefix Ethrunan is more difficult to deal with, and I should perhaps not have attempted its solution, if I had not seen on a map the name Rother applied to one of the head waters which, uniting near Stockport, form the Mersey. This stream is generally called the Etherow.[38] This is the nearest approach to Ethrunan that I have been able to meet with. If _rother_, by a kind of metathesis, is an equivalent to _ether_, perhaps I can detect two distinct remains of the word Ethrunanwerch, in the neighbourhood of Wearden. On the ordnance map we have, about a mile from Werden Hall, Rotherham Top, and a stream, recently diverted for the purpose of the Liverpool water supply, named the Roddlesworth. This word implies a place on the bank of a stream, and as the _d_ and _th_ are phonetic equivalents, it may be read Rothelsworth or Ethrunlesworth; indeed, Mr. Baines expressly says, "Withnall, or Withnell, also a part of the lordship of Gunoldsmores, containing Rothelsworth, a name derived from Roddlesworth, or Mouldenwater, a rapid stream." On the one-inch to the mile ordnance map there is a name which preserves the form of the first part of the word without the transposition, or metathesis, to which I have referred. Not far from Worden Hall is a small hamlet named "Ethrington." The fact that these names exist in the neighbourhood strengthens the probability that the etymology is not altogether fanciful, and consequently lends support to the presumption that the locality suggested may be the true site of Athelstan's great victory.
