Joan Mortimer

Joan Mortimer (1311 or 1312 – between 1337 and 1351) was an English noblewoman, probably third daughter of Roger Mortimer, 1st Earl of March. Betrothed in childhood to James Audley, she was arrested after Mortimer fled into exile in 1323, and confined at Sempringham Priory on twelve pence a week.

Freed after her father seized power with Queen Isabella in 1326, she married Audley in 1328 or 1329 at a double wedding. Her children included Nicholas Audley, later Baron Audley.
