Abigail Masham, Baroness Masham of Otes, was an English courtier. She was the cousin of Sarah, Duchess of Marlborough, and with her help, she got to the court of Queen Anne, where she was first named the “Lady of the Bedchamber.” She later became the Queen’s favorite and close friend, due to her warm nature and many abilities. After Sarah’s dismissal from the court, Abigail was named “Keeper of the Privy Purse.” After Anne’s death, she retired from court life and lived a private life until her death in 1734.
