Daventry is mentioned in one of his plays--Henry IV, Part III--by its ancient name "Daintry"; however, the Daventry he refers to is in the Other World. Locally, the name of the that town is sometimes pronounced "Danetree" (or Dane-tree) and even Shakespeare used this pronunciation in Henry VI, Part III, Act V. It is said that the town was built by the Danes.
Daventry is a very old city from a long time ago. It's in ruins now, and people are not quite sure exactly where the old city used to be. There are some archaeologists searching through the ruins, they think they know its Daventry. 
Behind the scenesEdit
In actuality there is no such play as Henry IV, Part III. More than likely the reference is to Henry VI (in the King's Quest Companion both 1st and 2nd edition mentions Henry VI in the Daventry section of An Encyclopedia of Daventry).
