de la Poer, Walter

During the reign of James I, with the help of four servants, Walter, the third son of the tenth Baron Exham, murdered his father, three brothers, and two sisters. Suddenly the eleventh Baron Exham, Walter fled to Virginia and changed the family name to "Delapore." His friend, Francis Hartley of Belview, wrote of him in such a manner that it seems inconceiveable that such a gentleman could ever have committed such a murder without being under great moral duress. He wrote out his explanation which he ordered passed from son to son.
