Born-deaf daughter of King James I of Scotland and Queen Jane Beaufort; she reportedly used sign language, even in public. Also known by the variant name Joanna. Betrothed at age 13 to her cousin, James Douglas, third Earl of Angus, in an arranged marriage, but he died before the wedding. Sent to France in 1445 for education at a nunnery. In 1457, wedded in another arranged marriage to James Douglas, 4th Lord Dalkeith and Earl of Morton, she becoming the Countess of Morton. Buried with her husband in the Morton Monument tomb in St. Nicolas Buccleauch Parish Church, Dalkeith, near Edinburgh. Appears as one of the characters in a novel by Emily Holt called Margery's Boy (1879) and in Niger Tranter's novel Black Douglas (1968). Jean's effigy on the Morton Monument is said to be the world's oldest image of a known named deaf person.
