 The term itself, according to Brockett, originated from all the North East coal mines.The catchment area for the term "Geordie" can include Northumberland and County Durham or be confined to an area as small as the city of Newcastle upon Tyne and the metropolitan boroughs of Tyneside.Scott Dobson, the author of the book "Larn Yersel Geordie", once stated that his grandmother, who was brought up in Byker, thought the miners were the true Geordies.
