Lady Eleanor de Bohun (c. 1366 – 3 October 1399) was the elder daughter and co-heiress with her sister Mary de Bohun, of their father Humphrey de Bohun, 7th Earl of Hereford. Her mother was Lady Joan Fitzalan, daughter of Richard FitzAlan, 10th Earl of Arundel and his second wife Eleanor of Lancaster.
Marriage

In 1376 she married Thomas of Woodstock, 1st Duke of Gloucester. Thomas was the youngest son of Edward III of England and Philippa of Hainault. Following their marriage, the couple went to reside in Pleshey Castle, Essex. Eleanor and her husband had the tutelage of her younger sister, Mary, who was being instructed in religious doctrine. This was being done in the hope that she would enter a convent, thus leaving her share of the considerable Bohun inheritance to Eleanor and Thomas.
