Earl's Creek marks the boundary between St Mary's parish, Rotherhithe and St Paul's parish, Deptford and their successors the London Borough of Southwark and the London Borough of Lewisham. It also marks the boundary between the historic counties of Kent and Surrey.[1] The river is named after the Earl of Gloucester in the time of Henry I.
