Herald's visitation

Heraldic visitations were tours of inspection undertaken by Kings of Arms (and more often by junior officers of arms (or Heralds) as deputies) throughout England, Wales and Ireland. Their purpose was to regulate and register the coats of arms of nobility and gentry and boroughs, and to record pedigrees. They took place from 1530 to 1688, and their records (akin to an upper class census) provide important source material for historians and genealogists.

By the fifteenth century, the use and abuse of coats of arms was becoming widespread in England. One of the duties conferred on William Bruges (or Brydges), the first Garter Principal King of Arms was to survey and record the armorial bearings and pedigrees of those using coats of arms and correct irregularities. Officers of arms had made occasional tours of various parts of the kingdom to enquire about armorial matters during the fifteenth century, however, it was not until the sixteenth century that the process began in earnest.

The first provincial visitations were carried out under warrant granted by Henry VIII to Thomas Benolt, Clarenceux King of Arms dated 6 April 1530. He was commissioned to travel throughout his province (i.e. south of the Trent) with authority to enter all homes and churches. Upon entering these premises, he was authorized to "put down or otherwise deface at his discretion... those arms unlawfully used". He was also required to enquire into all those using the titles of knight, esquire, or gentleman and decided if they were being lawfully used.
