Margaret Audley, Duchess of Norfolk
Margaret Howard (née Audley), Duchess of Norfolk (1540 – 9 January 1564) was the sole surviving child of Thomas Audley, 1st Baron Audley of Walden and Lady Elizabeth Grey, daughter of Thomas Grey, 2nd Marquess of Dorset and Margaret Wotton.
Elizabeth Woodville
Elizabeth Woodville (also spelled Wydville, Wydeville, or Widvile) (c. 1437 – 8 June 1492) was Queen consort of England, as the spouse of King Edward IV from 1464 until his death in 1483.
At the time of her birth, her family was of middle rank in the English social hierarchy.
Her mother Jacquetta of Luxembourg had previously been an aunt by marriage to Henry VI.
Elizabeth's first marriage was to a minor supporter of the House of Lancaster, Sir John Grey of Groby.
He died at the Second Battle of St Albans, leaving Elizabeth a widowed mother of two sons.
Her second marriage to Edward IV was a cause célèbre of the day, thanks to Elizabeth's great beauty and lack of great estates.
Edward was the first king of England since the Norman Conquest to marry one of his subjects, and Elizabeth was the first such consort to be crowned queen.
Her marriage greatly enriched her siblings and children, but their advancement incurred the hostility of Richard Neville, Earl of Warwick, 'The Kingmaker', and his various alliances with the most senior figures in the increasingly divided royal family.
This hostility turned into open discord between King Edward and Warwick, leading to a battle of wills that finally resulted in Warwick switching allegiance to the Lancastrian cause, and to the execution of Elizabeth's father Richard Woodville in 1469.
After the death of her husband in 1483, Elizabeth remained politically influential even after her son, briefly proclaimed King Edward V of England, was deposed by her brother-in-law, Richard III.
Edward and his younger brother Richard both disappeared soon afterward, and are presumed to have been murdered.
Elizabeth subsequently played an important role in securing the accession of Henry VII in 1485.
Henry married her daughter Elizabeth of York, ended the Wars of the Roses, and established the Tudor dynasty.
Through her daughter, Elizabeth was a grandmother of the future Henry VIII.
Elizabeth was forced to yield pre-eminence to Henry VII's mother, Lady Margaret Beaufort; her influence on events in these years, and her eventual departure from court into retirement, remains obscure.
Thomas Grey, 1st Marquess of Dorset
Thomas Grey, 1st Marquess of Dorset, 1st Earl of Huntingdon, 7th Baron Ferrers of Groby, (145520 September 1501) was an English nobleman, courtier and the eldest son of Elizabeth Woodville and her first husband Sir John Grey of Groby.
Her second marriage to King Edward IV made her Queen of England, thus elevating Grey's status at court and in the realm as the stepson of the King.
Through his mother's assiduous endeavours, he made two materially advantageous marriages to wealthy heiresses, the King's niece Anne Holland and Cecily Bonville, 7th Baroness Harington.
By the latter he had 14 children.
Henry Grey, 1st Earl of Stamford

Jane Shore
Elizabeth" Jane" Shore(" née" Lambert)( c. 1445 – c. 1527) was one of the many mistresses of King Edward IV of England, one of three whom he described as" the merriest, the wiliest, and the holiest harlots" in his realm.
She also became a concubine to other noblemen, including Edward's stepson, Thomas Grey, 1st Marquess of Dorset, and William Hastings, 1st Baron Hastings, his close friend and adviser.
Eleanor Grey
Lady Eleanor Grey( died before December 1503), was an English noblewoman, and the first wife of Sir John Arundell of Lanherne in Cornwall," the most important man in the county", being Receiver- General of the Duchy of Cornwall.
Their monumental brass in the church at St Columb Major in Cornwall was described by Dunkin( 1882) as" perhaps the most elaborate and interesting brass to be found in Cornwall."

Lady Eleanor was an ancestor of the later Barons Arundell of Wardour.
Elizabeth FitzHugh
Elizabeth FitzHugh( 1455/65- before 10 July 1507) was an English noblewoman.

Cecily Bonville, 7th Baroness Harington
Cecily Bonville, 7th Baroness Harington, 2nd Baroness Bonville (30 June 1460 – 12 May 1529) was an English peer, who was also Marchioness of Dorset by her first marriage to Thomas Grey, 1st Marquess of Dorset, and Countess of Wiltshire by her second marriage to Henry Stafford, 1st Earl of Wiltshire.
The Bonvilles were loyal supporters of the House of York during the series of dynastic civil wars that were fought for the English throne, known as the Wars of the Roses (1455–1487).
When she was less than a year old, Cecily became the wealthiest heiress in England after her male relatives were slain in battle, fighting against the House of Lancaster.
Cecily's life after the death of her first husband in 1501 was marked by an acrimonious dispute with her son and heir, Thomas Grey, 2nd Marquess of Dorset.
This was over Cecily's right to remain sole executor of her late husband's estate and to control her own inheritance, both of which Thomas challenged following her second marriage to Henry Stafford; a man many years her junior.
Their quarrel required the intervention of King Henry VII and the royal council.
Lady Jane Grey, Lady Catherine Grey and Lady Mary Grey were her great-granddaughters.
All three were in the Line of Succession to the English throne.
Jane, the eldest, reigned as queen for nine days in July 1553.
