1519–1536
In 1519, Elizabeth's daughters, Anne and Mary, were living in the French royal court as Ladies-in-waiting to the French Queen consort Claude. According to the papal nuncio in France fifteen years later, the French King Francis I had referred to Mary as "my English mare", and later in his life described her as "a great whore, the most infamous of all".
In the words of historian M.L. Bruce, both Thomas and Elizabeth "developed feelings of dislike" for their daughter Mary. In later years, Mary's romantic involvements would only further strain this relationship. Around 1520, the Boleyns managed to arrange Mary's marriage to William Carey, a respected and popular man at court. It was sometime after the wedding that Mary became mistress to Henry VIII (the exact dates as to when the affair started and ended are unknown), although she never held the title of "official royal mistress," as the post did not exist in England. It has long been rumoured that one or both of Mary Boleyn's children were fathered by Henry and not Carey. Some historians, such as Alison Weir, now question whether Henry Carey was fathered by the King. Few of Henry's mistresses were ever publicly honoured, except Elizabeth Blount, who was mentioned in Parliament and whose son, Henry Fitzroy, was created Duke of Richmond and Somerset in an elaborate public ceremony in 1525. Henry's relationship with Mary was so discreet that within ten years, some observers were wondering if it had ever taken place.
In contrast to Mary, Elizabeth's other daughter, Anne, is thought to have had a close relationship with her mother. Elizabeth had been in charge of her children's early education, including Anne's, and she had taught her to play on various musical instruments, to sing and to dance, as well as embroidery, poetry, good manners, household management, arithmetic, grammar, history, reading, spelling, writing and some French. In 1525, Henry VIII fell in love with Anne, and Elizabeth became her protective chaperone. She accompanied Anne to Court, since Anne was attempting to avoid a sexual relationship with the King. Elizabeth travelled with Anne to view York Place after the fall of the Boleyn family's great political opponent, Cardinal Thomas Wolsey – an intrigue which had given Anne her first real taste of political power. She was crowned queen four years later.
Elizabeth remained in her daughter's household throughout her time as queen consort. Tradition has it that Anne's daughter, Elizabeth I, was named after her maternal grandmother. However, it is more likely that she was named after Henry's mother, Elizabeth of York, although the possibility that she was named after both grandmothers cannot be ruled out.
Elizabeth Boleyn sided with the rest of the family when her eldest daughter, Mary, was banished in 1535 for eloping with a commoner, William Stafford. Mary had initially expected her sister's support (Anne had been Mary's only confidante within the Boleyn family since 1529), but Anne was furious at the breach of etiquette and refused to receive her.
Only a year later, the family was overtaken by a greater scandal. Elizabeth's younger daughter, Anne, and her only living son, George, were executed on charges of treason, adultery, and incest. Anne's two chief biographers, Eric Ives and Retha Warnicke, both concluded that these charges were fabricated. They also agree that the King wanted to marry Jane Seymour. Beyond this obvious fact, the sequence of events is unclear and historians are divided about whether the key motivation for Anne's downfall was her husband's hatred of her or her political ambitions. Despite the claims of several recent novels, academic historians agree that Anne was innocent and faithful to her husband. Nonetheless, the judges obeyed the King, condemning Anne, George Boleyn and four others to death. Elizabeth's husband Thomas Boleyn and brother Thomas Howard, 3rd Duke of Norfolk provided no help to the condemned. The accused men were beheaded by the axe on 17 May 1536 and Anne was executed by a French swordsman two days later.
