William Verney (d. 1489) is said to have had licence c. 1473 to encircle his house at Fairfield with a wall and seven round towers. (Dunning)
12 Edw. IV. this William (William de Vernai IV) had a licence to build a wall and seven round towers about his mansion-house at Fairfield, and to inclose two hundred acres of ground for a park. (Collisonunreferenced)
This seems a quite detailed reference but it is not enrolled. Virtually all licences to crenellate of this date also had licence to empark but the mention of 'seven round towers' is a most unusual detail Gatehouse
is not aware of in any other licence. Of licences said to be given but not enrolled this seems the most likely, because of this mention of a licence to empark although Gatehouse
also can not find that.
