The Roman Map of Britain Durocornovio (?) or Duroconovio Wanborough, Wiltshire

Durocornovio (AI 485₅ Iter xiii)

Opposite the Roman station SU 196 850 is a stream, a branch of the upper Cole.
ERN p 128, under Dork
Dorcan stream is recorded as 

(innan, andlang) Dorceri, (wythinne, along) Dorkerne, the Dorkeherne
(translated 'angulus tenebrosus') 901 (14th) BCS 598, in boundaries of
Chiseldon,

(of) Dorcyn 940 (15th) BCS 754 (Liddington)

Dorternebrok' 955 (c.1350) BCS 904, in boundaries of Badbury near Chiseldon,

(innan) Dorcan 1043-53.

It is worth noting that Ekwall thought corrupt the Dorcern- forms which most strongly resemble the Roman settlement's recorded name. Modern Dorcan SU1984 is not on the 1882 OS map, the nearest
place-name being Lower Liddington Wick.

Conventional wisdom interprets the name as 'fort of the Cornovii' - Wanborough is well outside of any postulated Cornovii territory.
