Daintry

Daintry is the ancient name for the town of Daventry in England.

Background
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" and even Shakespeare used this pronunciation in Henry VI, Part III, Act V.

Behind the scenes
In actuality there is no such play as Henry IV, Part III in the real world. More than likely the reference is to Henry VI.
