Facts and Events
Joan de Geneville, 2nd Baroness Geneville, Countess of March, Baroness Mortimer (2 February 1286 – 19 October 1356), also known as Jeanne de Joinville, was the daughter of Sir Piers de Geneville and Joan of Lusignan. She inherited the estates of her grandparents, Geoffrey de Geneville, 1st Baron Geneville, and Maud de Lacy, Baroness Geneville. She was one of the wealthiest heiresses in the Welsh Marches and County Meath, Ireland. She was the wife of Roger Mortimer, 1st Earl of March, the de facto ruler of England from 1327 to 1330. She succeeded as suo jure 2nd Baroness Geneville on 21 October 1314 upon the death of her grandfather, Geoffrey de Geneville.
As a result of her husband's insurrection against King Edward II of England, she was imprisoned in Skipton Castle for two years. Following the execution of her husband in 1330 for usurping power in England, Joan was once more taken into custody. In 1336, her lands were restored to her after she received a full pardon for her late husband's crimes from Edward II's son and successor, Edward III of England.
