From Shrewsbury, in Shropshire, the A5, following the route of the old highway from London to Holyhead, takes you north to Oswestry. Continuing north on the A5, you pass a small town called Chirk. If you continue north on the A483, you pass a place called Trevor on the left, and continue to Wrexham. But if you stay on the A5 from Chirk, you turn west into the mountains of Wales, and come to a village called Llangollen. Here in the early middle ages lived several generations of Welshmen, descendants of Tudor Trevor and ancestors of Edward Hosyer. This is the area of the Marches, the border area between England and Wales. Above Llangollen are the ruins of the Dinas Bran castle. Near many of the towns in this area are other castles built to protect each side from the other.
"The beautiful vale of Llangollen, though so well known for its natural attractions, has not been so carefully scrutinised by archaeologists as could be wished. It would seem as though the Abbey of Valle Crucis and the Pillar of Eliseg, being of course the most remarkable remains, attracted the learned westward, so that the portion of the Vale which lies to the East has escaped investigation. And yet there are many places of interest whose history might repay the antiquary for the trouble of searching after it. Little has been written about old Pengwern hall, traditionally said to have been the birthplace and seat of Tudor Trefor. It is true that at the present time there are few traces of antiquity left about it." 
This category focuses people in the fifty mile area around Llangollen, Wales between the years 900 and 1500. This would include Oswestry, Chirk, the area controlled by the Prince of North Wales, the Norman/English Overlords in Shropshire, etc.
