<P> As Queen Elizabeth's sons, the Princes in the Tower, were presumed murdered, it was agreed that Margaret's son, Henry, would be betrothed to Elizabeth of York, the eldest daughter of Elizabeth and Edward IV, thus creating a marriage alliance with potential to attract both Yorkist and Lancastrian support . </P> <P> Margaret's husband Stanley, despite having fought for Richard III during the Buckingham rebellion, did not respond when summoned to fight at the Battle of Bosworth Field in 1485, remaining aloof from the battle, even though his eldest son, George Stanley (styled Lord Strange), was held hostage by Richard . After the battle, it was Stanley who placed the crown on the head of his stepson (Henry VII), who later made him Earl of Derby . Margaret was then styled "Countess of Richmond and Derby". She was invested as a Lady Companion, Order of the Garter (LG) in 1488 . </P> <P> During this period Margaret and the Stanley family endowed the building of chapels in Wales . Like Edward IV and his court, she was also involved with the advances in printing of William Caxton and his successor Wynkyn de Worde, not only as a patroness but for her own acquisition . The first book she commissioned from Caxton in 1483 was the 13th - century French romance Blanchardin et Englantine, which mirrored fairly closely the match she was forging in secret between her son Henry and Elizabeth of York, with the aid of Elizabeth Woodville, then in sanctuary from Richard III in Westminster Abbey . Six years later, after Richard's defeat to Henry at Bosworth, she commissioned an English translation of the romance from Caxton: it heralded the beginning of a period of Tudor patronage . Apart from encouraging book production and building her own library, Margaret also involved herself as a translator, mostly of French religious texts . </P> <P> Later in her marriage, the Countess preferred living alone . In 1499, with her husband's permission, she took a vow of chastity in the presence of Richard FitzJames, Bishop of London . Taking a vow of chastity while being married was unusual but not unprecedented; around 1413, Margery Kempe also negotiated a vow of chastity with her husband . The Countess moved away from her husband and lived alone at Collyweston, Northamptonshire (near Stamford). She was regularly visited by her husband, who had rooms reserved for him . Margaret renewed her vows in 1504 . </P>
