Isabella Plantagenet

Isabella of England, also called Elizabeth (1214-December 1, 1241) was the daughter of King John of England and Isabella of Angouleme. She was married to Frederick II, Holy Roman Emperor in 1235, who kept her hidden away in seclusion. When her brother, Richard, Earl of Cornwall, passed through Sicily returning from the Crusades, he had to beg Frederick to see Isabella and speak with her for a few moments.

She bore four children, all of whom died aside from a daughter, Margaret of Sicily (1237–1270). Isabella died in childbirth at Foggia along with her child in 1241, and according to Thomas Costain, Frederick buried her beside one of his Saracen mistresses.

A later Isaballa Plantagenet (1332-1382) was the daughter of Edward III of England, and wife of Enguerrand VII of Coucy, 1st Earl of Bedford.
