Shortly after the Norman conquest of England, between 1069 and 1070, William the Conqueror led a military campaign against the Saxon Earl Edwin, who ruled England north of the River Mersey. On the campaign's successful conclusion, William gave his kinsman Roger de Poictou all of the land between the River Mersey and the River Ribble. Part of this land was in turn given to Albert de Greslet, who towards the end of the 12th century, bestowed as much land as a team of oxen could plough in one-year on Orme Fitz Seward, the son of Edward Aylward. It is probable that the name Urmston is derived from Orme's Easton, or Ormestun, the "tun" or dwelling of Orme Fitz Seward.
