No mention has been found of Ely as a town before the time of the virgin queen S. Etheldreda. The district known as the Isle of Ely--which now includes the whole of the northern part of Cambridgeshire above the River Ouse, together with a few parishes east of that river that are in the county--is spoken of at the time of the marriage of the princess as if it were a district well known and perhaps of some importance, as it was assigned to her as a dowry. Some writers have held that the expression the Isle of Ely applied only to the rising ground.
