The Domesday Book records the population of Bradfield St. Clare in 1086 to be 76; this includes Bradfield Combust and Bradfield St George. It was at that point held by the St Cleer family (whose name it still bears) on behalf of the Abbey of Bury St Edmunds. By 1493 it was owned by John Jerveys, and by 1552 was linked to the Davers family.[2][3]
A Church of England school was built in the village 1875, and closed in the 1950s.
It has been speculated that the field of Hellesden, which may be a corruption of Hagelisdon, within the parish, was the site of the martyrdom of St Edmund.[2]
In 1801 the village had 131 inhabitants, rising to 226 by 1831 and remaining stable for several decades. By 1901 the population had declined again to 165, and remained at a similar size up to 1981.[2]
