Mary had been unhappy with her marriage to Louis, as at this time she was almost certainly already in love with
Charles Brandon, 1st
Duke of Suffolk. Henry knew of his sister's feelings but wanted any future marriage to be to his advantage. When he sent Brandon to bring Mary back to England in late January 1515, he made the Duke promise that he would not propose to her. However, the couple married in secret in France on
March 3 1515. Technically this was
treason, as Brandon had married a Royal Princess without Henry's consent. The King was outraged, and the
Privy Council urged that Brandon should be imprisoned or executed. Due to the intervention of
Wolsey, and Henry's affection for both his sister and Brandon, the couple were let off with a heavy fine. They were officially married on
May 13 1515 at
Greenwich Palace.
After the marriage, Mary spent most of her time at the Duke's country seat of Westhorpe Hall in
Suffolk. She and Brandon had three children:
*
Henry Brandon, 1st
Earl of Lincoln (
March 11 1516 –
March 8, 1534)
*
Lady Frances Brandon (
July 16 1517 –
November 20 1559), who married
Henry Grey, 3rd
Marquess of Dorset, and was the mother of
Lady Jane Grey
*
Lady Eleanor Brandon (
1519 –
September 27, 1547), who married
Henry Clifford, 2nd
Earl of Cumberland.
Relations between Henry VIII and Mary were strained in the late
1520s when she opposed the King's attempt to obtain an
annulment of his marriage to
Catherine of Aragon, whom Mary had known for many years. She had developed a strong dislike for the future Queen
Anne Boleyn, whom she had first encountered in France.
Mary died at Westhorpe Hall, Westhorpe,
Suffolk on
June 25 1533, and was initially buried at the
abbey at
Bury St Edmunds, Suffolk. Her body was moved to nearby St. Mary's Church, also in
Bury St Edmunds, when the abbey was destroyed during the
Dissolution of the Monasteries.
