The River Witham seems to have joined The Haven after the flood of September 1014, having abandoned the port of Drayton, on what subsequently became known as Bicker Haven. The predecessor of Ralph the Staller owned most of both Skirbeck and Drayton, so it was a relatively simple task to transfer his business from Drayton, but Domesday Book in 1086 still records his source of income in Boston under the heading of Drayton, so Boston's name is not mentioned. The Town Bridge still maintains the preflood route, along the old Haven bank.
