Individual Details

The daughter of King Edward I and Eleanor of Castile, Joan was born at Acre, Isreal while her father was on crusade. She married Gilbert of Clare, 3rd earl of Gloucester on April 30, 1290 at Westminster Abbey. They had 4 children before Gilbert's death in 1295. She then married Ralph Monthermer, 1st baron Monthermer, a knight in her household, in 1297 without her father's consent. Enraged at his daughter's lowly second marriage, Edward I had Monthermer thrown in prison. Joan begged for his release, and the king relented, giving Monthermer the title earl of Gloucester. Joan died at her manor in Clare at the age of 35. Though the exact cause of her death is unknown, some historians have recently theorized she may have died giving birth to a fifth child by Monthermer. The remains of an altar recess on the ruins of the south wall of the abbey are thought to be Joan's tomb. A friar reported that in 1359, Joan's daughter Elizabeth DeBurgh inspected her mother's tomb and found the remains to be incorrupt. Since then, there have been reports of miraculous healing of toothache, fever, and back pain there.
