In 735, the northern ecclesiastical province of England was established, with the archbishopric at York. There were only three bishops under York: Hexham, Lindisfarne and Whithorn, whereas Canterbury had the 12 envisaged by St Augustine. The Diocese of York roughly encompassed the counties of Yorkshire and Lancashire. Hexham covered County Durham and the southern part of Northumberland up to the River Coquet, and eastwards into the Pennines. Whithorn covered most of Dumfries and Galloway region west of Dumfries itself. The remainder, Cumbria, northern Northumbria, Lothian and much of the Kingdom of Strathclyde formed the diocese of Lindisfarne.
