Information requested re wild horses at Hergest, Kington, Herefordshire.

“Do you know who one could/should contact, or where to find further info about the history of the wild horses who are at Hergest up above Kington in northwest Herefordshire ?”

Can you help? If so, please put your reply either on the forum or on the Hereford Equestrian Facebook page.  Both these pages display the question. Many thanks!
