No part of Stockport appears in the Domesday Book of 1086. The area north of the Mersey was part of the hundred of Salford, which was poorly surveyed. The area south of the Mersey was part of the Hamestan hundred. Cheadle, Bramhall, Bredbury, and Romiley are mentioned, but these all lay just outside the town limits. The survey includes valuations of the Salford hundred as a whole and Cheadle for the times of Edward the Confessor, just before the Norman invasion of 1066, and the time of the survey. The reduction in value is taken as evidence of destruction by William the Conqueror's men in the campaigns generally known as the Harrying of the North. The omission of Stockport was once taken as evidence that destruction was so complete that a survey was not needed.
