Short answers, pulled from the story.
Anne Gainsford was a 16th-century courtier who served as lady-in-waiting to Queen Anne Boleyn, entering her household before 1528. She was a close enough companion that Anne Boleyn called her by the pet name Nan. After Anne Boleyn's execution in 1536, she served Anne Boleyn's successor, Jane Seymour, in the same capacity.
In 1528, Anne Boleyn lent Anne Gainsford a proscribed copy of Tyndale's The Obedience of a Christian Man. Her betrothed, Sir George Zouche, took it from her hands in jest, and it was found by Richard Sampson, Dean of the Chapel Royal, who gave it to Cardinal Wolsey. Anne Boleyn retrieved the book from the King and persuaded him to read it; Henry called it a book "for me and all kings to read".
When Anne Boleyn showed her a book of ancient prophecies in 1530 containing a crude drawing of herself without a head, Anne Gainsford reportedly said: "If I thought it true, though he were an emperor, I would not myself marry him." Anne Boleyn dismissed the book as a bauble.
Anne Gainsford died before the 16th of July 1548. That date comes from her husband Sir George Zouche's last will, in which he referred to a woman named Elleyn as his current wife, confirming he had remarried after Anne's death.
The 19th-century editor Samuel Weller Singer identified Anne Gainsford as the serving woman whose reminiscences informed George Wyatt's biography of Anne Boleyn. Researcher Sylvia Barbara Soberton later proved this was wrong because Anne Gainsford died before Wyatt was born, around 1553. Weller Singer was likely misled by the similarity between the banned-book story linked to Anne Gainsford in John Foxe's Book of Martyrs and a different banned-book story in Wyatt's biography.
Anne Gainsford and Sir George Zouche made their principal home at Codnor Castle in Derbyshire. They had eight children together, including John Zouch of Codnor, Margaret Zouch, George Zouch, William Zouch, and daughters Lucy, Frances, Anne, and Audrey.
