“ Herefordshire probably originated as a shire in the time of Æthelstan, and is mentioned in the Saxon Chronicle in 1051. In the Domesday Survey parts of Monmouthshire and Radnorshire are assessed under Herefordshire, and the western and southern borders remained debatable ground until with the incorporation of the Welsh marches in 1535 considerable territory was restored to Herefordshire and formed into the hundreds of Wigmore, Ewyas Lacy and Huntingdon, while Ewyas Harold was united to Webtree. At the time of the Domesday Survey the divisions of the county were very unsettled. ”
