Short answers, pulled from the story.
Elizabeth Boleyn was an English noblewoman born around 1480, the elder daughter of Sir Thomas Howard, who later became the 2nd Duke of Norfolk. She is best remembered as the mother of Anne Boleyn, Queen of England, and the maternal grandmother of Elizabeth I.
Elizabeth Boleyn had three children who survived to adulthood: Mary Boleyn, George Boleyn (Viscount Rochford), and Anne Boleyn. Two other sons, Thomas (born 1496) and Henry (born 1500), died during the sweating sickness outbreak of 1506.
Elizabeth Boleyn became Viscountess Rochford in 1525, Countess of Ormond in 1527, and Countess of Wiltshire in 1529. Each title reflected the rising status of her husband Thomas Boleyn at the Tudor court.
Anne Boleyn's two principal biographers, Eric Ives and Retha Warnicke, both concluded that the charges of treason, adultery, and incest were invented. Academic historians broadly agree that Anne was innocent and faithful to her husband, and that Henry VIII wished to marry Jane Seymour.
Rumours circulated that Elizabeth Boleyn had once been Henry VIII's mistress, with some even suggesting that Anne Boleyn might be Henry's daughter. Henry denied the claim, and it appears nowhere in the dispensation he sought for his marriage to Anne. Most historians trace the rumour to a confusion with Elizabeth Blount, Henry's publicly acknowledged mistress.
Elizabeth Boleyn is buried in the Howard family chapel at St Mary's Church, Lambeth. The church was decommissioned in 1972 and has since become the Garden Museum.
