 For several centuries, the part of Suffolk centred on Exning was almost an enclave of the county within the confines of Cambridgeshire.The parish of Newmarket All Saints was transferred from Cambridgeshire to this virtual enclave in 1894, but it continued to be practically detached until boundary changes in the area widened considerably the "bridge" between it and the rest of Suffolk a hundred years later.Exning is reputed to have been the birthplace of Saint Ethelreda, to whom the cathedral at Ely is dedicated, though this is disputed.
