Gyrwas
The name Gyrwe means 'fen-dweller'. The territory of the Gyrwas included Lindisfarne, Hatfield, Nottinghamshire, Northern Cambridgeshire, Huntingdonshire, and as far south as Peterborough in Northamptonshire. The area around Jarrow was in their territory as well. The Fens supplied the Gyrwas with fish and gamebirds but they lived on the drier lands and islands nearby.
