Mary Boleyn was an English courtier and the sister of Anne Boleyn. She spent time at the French court before marrying Sir William Carey in 1520 and later became a mistress of Henry VIII, although the exact duration and chronology of their relationship are uncertain.
Mary had two children during her marriage to Carey, Catherine and Henry Carey; claims that Henry VIII fathered either child remain unproven. After Carey’s death she secretly married William Stafford, a match beneath her family’s expectations that led to her temporary exclusion from court.
Alison Weir’s Mary Boleyn reconstructs the poorly documented historical life of Anne Boleyn’s sister, testing the evidence for Mary’s relationships at the French and English courts and her affair with Henry VIII. Philippa Gregory’s The Other Boleyn Girl makes Mary a principal fictional viewpoint, contrasting her intimacy with Henry and family obligations with Anne’s more dangerous rise. Weir’s The Boleyn Secret and Anne Boleyn place Mary within the sisters’ early court world and the family ambitions surrounding Anne’s ascent. Rozsa Gaston’s The Queen’s Maid uses the consequences of Mary’s choices as part of Anne’s education in how sexuality, reputation and dynastic politics operate at court.
