Introduction (pp. v-vi:
"Investigations have recently [pre 1851] been made in England to ascertain [William Ward's] paternity, but without any satisfactory result. They are still being made for that purpose, and to learn the names of his wives and births of his children, who came here with him...
"Information already received, renders it improbable that he came from Yorkshire, although it is quite certain, that his early ancestors were of that place. Seven hundred and ten distinguished persons, each bearing but one name, accompanied William, the Conqueror, from Normandy to the conquest of England in 1066; a record of all whose names is yet preserved. Among the number was 'Ward, one of the noble Captains.' This is the earliest period in which the name is found in English history, and the first which appears there with an additional name was William de la Ward, residing in Chester, in 1175.
"From 1349, a succession of eleven generations of one family is found there [Chester], in each of which, the name of the head of the family was, in the first, Ralph; in the second, Richard; in the third, John; in the fourth, John; in the fifth, Richard, in the sixth, William; in the seventh, Thomas; in the eight, Thomas; in the ninth, John; in the tenth, Richard; and in the eleventh, Thomas, who had sons John and William-- these were prevailing names in the early families descended from William of Sudbury, and are yet retained to a considerable extent in the families of his descendants to the present time.
"The Wards of Yorkshire spread into the adjoining counties of England; those of Durham, whence it may be, came William Ward, afterwards of Sudbury, were descendants of the Yorkshire Wards-- the arms anciently belonging to the family here, were Azure, a cross baton, or Crest, wolfs head erased-- and such were those of the Durham Wards. http://books.google.com/books?id=yHhZAAAAMAAJ&dq=%22William+Ward%22&pg=PR1
