Mary Fiennes, Lady Norris

Mary Fiennes (1495–1531) was an English noblewoman and the wife of Sir Henry Norris who was executed for treason as one of the alleged lovers of her cousin, Anne Boleyn, the second wife of King Henry VIII of England. Mary lived for six years at the French court as a Maid of Honour to queens consort, Mary Tudor and Claude of France, queen consort of Francis I of France.

Mary was born at Herstmonceux Castle in Sussex in 1495, the only daughter of Sir Thomas Fiennes, 8th Baron Dacre and Anne Bourchier. She had two younger brothers, Sir Thomas and John. Her mother was an elder half-sister of Elizabeth Howard and Lord Edmund Howard, making queen consorts Anne Boleyn and Catherine Howard a cousin of Mary. Her paternal grandmother, Alice FitzHugh, was sister to Elizabeth FitzHugh, grandmother of another queen consort of Henry VIII, Catherine Parr.

In 1514, Mary was appointed a Maid of Honour to Princess Mary Tudor and accompanied her to France when the latter married King Louis XII of France; afterwards she served in the capacity to Queen Mary's successor, Queen Claude, consort of the new king Francis I of France. Among her fellow Maids of Honour were her cousins, Mary (a mistress of Henry VIII) and Anne Boleyn.
