Overview
Mary Shelton (1510-1515 – 1570/71) was one of the contributors to the Devonshire manuscript. Either she or her sister Madge Shelton may have been a mistress of King Henry VIII.
Family
Both Margaret and Mary were daughters of Sir John Shelton and his wife Anne, the sister of Thomas Boleyn, 1st Earl of Wiltshire. Thomas Boleyn was the father of Anne Boleyn, second Queen consort to Henry VIII of England. Margaret and Mary were thus first cousins of the Queen. Princess Mary sent her New Year's Day gifts of a sum of money, 7 shillings 6 pence, in January 1537 and 1540.
Mary wrote poems, and it was said she was chided "for writing 'ydill poesies' in her prayerbook". She was part of a social group which included the poets Sir Thomas Clere (d. 14 April 1545), Henry Howard, Earl of Surrey, and Thomas Wyatt, with all of whom she was romantically linked. In an epitaph he composed at the death of Sir Thomas Clere, Surrey identified Mary as Clere's "beloved". Mary's two closest friends were Lady Margaret Douglas, a niece of King Henry VIII, and Mary Howard, Duchess of Richmond, wife of the King's illegitimate son, Henry Fitzroy, Duke of Richmond. Shelton was the main editor and a contributor to the famous Devonshire MS, where members of their circle wrote poems they enjoyed or had composed.
Her father, John Shelton (1472 – 21 December 1539), was the son of Sir Ralph Shelton and Margaret Clere. He was a high sheriff in 1504, and knighted in 1509. Her siblings were John, Ralph, Elizabeth, Anne, Gabriella, Emma, Thomas, Margaret and Amy Shelton (Mary was one of 10 children). She was married three times and had seven children. After the death of her fiancé, Thomas Clere, she married Anthony Heveningham of Ketteringham, her first cousin. She had seven children with Heveningham: Arthur, John, Abigail, Bridget, Elizabeth, Mary and Anne. Another son, Anthony, died on 22 November 1557. Mary's final marriage was to Phillip Appleyard.
