I am presently translating and editing the Register of William Waynflete, Bishop of Winchester 1447/86, sometime Chancellor of England, Provost of Eton, and founder of Magdalen College, Oxford. I am also creating a Liber Vitae of the 10,000 people in the Register. One such is Henry Strother. I have most of the information on him. He was educated at University College, Oxford MA, DD, but I need information on his probable family home. Emden in his Biographical Register of the University states that he came from the diocese of Durham. However this is partially inaccurate. Strother came from modern Northumberland but that part which was under the spirituality of Archbishop of York ie Hexhamshire. I am therefore interested in the medieval boundaries of this shire, particularly near Gunnerton. Was Gunnerton burn the boundary between the Liberty of Hexhamshire and Northumberland?
