The Hundred Rolls are a census of England and parts of what is now Wales taken in the late thirteenth century. Often considered an attempt to produce a second Domesday Book, they are named after the hundreds by which most returns were recorded. The Rolls include a survey of royal privileges taken in 1255, and the better known surveys of liberties and land ownership, taken in 1274–5 and 1279–80, respectively. The two main enquiries were commissioned by Edward I of England to record the adult population for judicial and taxation purposes.

Below listed some of the names appearing in the Hundred Rolls of 1274-75, around the time that the adoption of surnames, after the Norman fashion, became a requirement. The Rolls have survived for only certain counties but a range of spelling is already apparent.
