Economic success also saw the town expand. New Street is first recorded in 1296, Moor Street was created in the late 13th century and Park Street in the early 14th century. Population growth was driven by rural migrants attracted by the opportunity of establishing themselves as traders, free from duties of agricultural labour. Analysis of rentals suggest that two-thirds came from within of the town, but others came from further afield, including Wales, Oxfordshire, Lincolnshire, Hampshire and even Paris. There is also some evidence that the town may have had a Jewish population before the Edict of Expulsion of 1290.
