Elizabeth Cheney (April 1422 - the 25th of September 1473) was an English gentrywoman from Fen Ditton, Cambridgeshire. She is historically significant as the great-grandmother of three of Henry VIII's wives: Anne Boleyn, Jane Seymour, and Catherine Howard, making her a great-great-grandmother of both Queen Elizabeth I and King Edward VI.
Elizabeth Cheney's first husband was Sir Frederick Tilney of Ashwellthorpe, Norfolk, who died in 1445. Her second husband, whom she married shortly before the 1st of December 1446, was Sir John Say of Broxbourne, Hertfordshire, who served as Speaker of the House of Commons.
Elizabeth Cheney bore eight children in total. She had one daughter, Elizabeth Tilney, from her first marriage to Sir Frederick Tilney. From her second marriage to Sir John Say she had seven children: three sons (Sir William Say, Thomas Say, and Leonard Say) and four daughters (Anne, Mary, Margaret, and Katherine Say).
Elizabeth Cheney is the great-grandmother of Anne Boleyn. Her daughter Elizabeth Tilney married Thomas Howard, Earl of Surrey, and their daughter Elizabeth Howard became the mother of Anne Boleyn.
Elizabeth Cheney's daughter Anne Say married Henry Wentworth, and their daughter Margery Wentworth became the mother of Jane Seymour. This makes Elizabeth Cheney the great-grandmother of Jane Seymour and great-great-grandmother of King Edward VI.
