Cosford was a hundred of Suffolk, consisting of 30712acres.[1]
The hundred consisted of Hadleigh, the only town of any size, and seventeen other parishes in western Suffolk. The area is undulating and agriculturally-fertile with clay soil, watered by the River Brett and its tributary streams. It is about 12miles in length from north to south and around five wide, and is bounded by the Hundreds of Samford, Babergh, Thedwestry, Stow and Bosmere and Claydon.
Cosford was in Coxford Union in the Liberty of St Edmund and in the Deanery and Archdeaconry of Sudbury. The area was until the nineteenth century part of the diocese of Norwich until it was moved to that of Ely. Hadleigh itself however is a peculiar of the Archbishop of Canterbury.
Listed as Cursforde in the Domesday Book and subsequently known for a period as Corsford or Corsforth, the name Cosford means "ford of the river Cors or Corsa".[2]
