Joan de Fiennes also descended from John of Brienne and Berengaria of León, herself the granddaughter of Eleanor of England, Queen of Castile.
[citation needed] She married, for a second time, Edmund of Woodstock, 1st Earl of Kent,[3] the sixth son of King Edward I of England, and the second by his second wife Margaret of France.
[9] When King Edward III of England reached his majority and overthrew the regents a few months later, he took in Margaret and her children and treated them as his own family.
[4] Margaret briefly succeeded her brother as Baroness Wake of Liddell in 1349, but died during an outbreak of the plague in September 1349.
Margaret is a character in the 2014 novel A Triple Knot by Emma Campion which primarily focuses on her daughter Joan of Kent's struggle to validate her secret marriage to Thomas Holland after her family forces her into a marriage with William Montacute, and her close, often uncomfortable relationship with her cousin and future husband Edward, Prince of Wales.
