Question: Who is the stepmother of Arthur Plantagenet, 1St Viscount Lisle?

Knowledge 1: Arthur Plantagenet, 1st Viscount Lisle
Arthur Plantagenet, 1st Viscount Lisle, KG (died 3 March 1542) was an illegitimate son of the English king Edward IV, half-brother-in-law of Henry VII, and an uncle of Henry VIII, at whose court he was a prominent figure and by whom he was appointed Lord Deputy of Calais (1533–40).The survival of a large collection of his correspondence in the Lisle Letters makes his life one of the best-documented of his era. [SEP] Knowledge 2: Edward IV of England
Edward IV (28 April 1442 – 9 April 1483) was King of England from 4 March 1461 to 3 October 1470, and again from 11 April 1471 until his death.His father, Richard of York, leader of the Yorkist faction, was a lineal descendant of Edward III and until 1453, heir presumptive to Henry VI, from the ruling House of Lancaster, or Lancastrians.Less than a year old when he came to the throne in September 1422, Henry's minority was marked by political infighting within the Regency council.After 1437, he ruled in his own right but his weak and indecisive personality did little to mitigate factional conflict.Shortly after the birth of his son Edward of Westminster in 1453, Henry suffered a complete mental breakdown and the government descended into chaos.Conflict between Yorkists and Lancastrians led to civil war in 1455.This continued intermittently until 1485 and is collectively known as The Wars of the Roses.After Richard was executed in December 1460, Edward became head of the family; with the support of the Earl of Warwick, or 'The Kingmaker', he deposed Henry and was crowned king in June 1461.Divisions developed after Edward's marriage to Elizabeth Woodville in 1464; Warwick switched sides in 1470 and restored Henry to the throne.Edward fled to Flanders, but returned to England in March 1471, winning victories at Barnet in April and Tewkesbury inMay. Warwick, Henry's heir Edward of Westminster and other senior Lancastrians were killed, while Henry died in the Tower of London a few days later.England remained relatively peaceful until Edward's death in 1483.His two minor sons, Edward and Richard were subsequently declared illegitimate by his younger brother, the Duke of Gloucester, who became Richard III.
