Mesolithic and Neolithic artefacts have been found in the area surrounding Corby and human remains dating to the Bronze Age were found in 1970 at Cowthick. The first evidence of permanent settlement comes from the 8th century when Danish invaders arrived and the settlement became known as "Kori's by" – Kori's settlement. The settlement was recorded in the Domesday Book of 1086 as "Corbei". Corby's emblem, the raven, derives from an alternative meaning of this word. These Danish roots were recognised in the naming of the most southern of the town's housing estates, Danesholme, around which one of the Danish settlements was located.
