Isabel Agard, died after 1520, was a member of the Agard family of Foston, Staffordshire. She married John Stonor (1480-1550). She may be the Mrs. Stonor who was with Anne Boleyn in the Tower of London in 1536 and/or the Mrs. Stonor who was Mother of Maids under Henry VIII's next four queens. See the entry for Isabel's sister-in-law, Margaret Foliot for more speculation on this identification. Isabel was the mother of Francis Stonor (1520-1564) and Henry Stonor. Retha Warnicke identifies Mrs. Stonor as "perhaps the wife of John, the king's sergeant at arms," in her The Rise and Fall of Anne Boleyn.
