The name Mangevilain occurs in Yorkshire as early as the 16th year of the reign of Henry I of England, but is very rare, and (failing evidence of any place named Mangeville) seems to be merely a variant spelling of Magnevillain. The meaning may be simply "of Magneville", de Magneville; but the family of a 14th-century bishop of Nevers were called both "Mandevilain" and "de Mandevilain", where Mandevilain seems a derivative place-name, meaning the Magneville or Mandeville district. The name "de Mandeville "might be suggested to de Bourgogne by that of his fellow-culprit Mangevilayn, and it is even possible that the two fled to England together, were in Egypt together, met again at Liège, and shared in the compilation of the "Travels".
