  Research Notes:

King John confirmed "castrum de Ellesmara" to "Lewelino principi Norwallie in maritagium cum Johanna filia nostra" by charter dated 16 Apr 1205. Her husband sent her to make peace with the king her father in 1211 when the latter was attacking North Wales. She was legitimated in 1226: Pope Honorius III gave dispensation to “Joan wife of Leuwelin prince of North Wales, daughter of king John declaring her legitimate, but without prejudice to the king or realm of England”, dated 29 Apr 1226. She and her son David did homage to King Henry III in 1229. The Chronicle of the Princes of Wales records that "William Bruse was hanged by Llywelyn son of Iorewerth, having been caught in the chamber of the prince with the princess Jannet, daughter of King John and wife of the prince" in 1230.

The Annales Cambriæ record the death in 1237 of "domina Johanna filia regis Angliæ et uxor Lewilini principis Walliæ" and her burial "apud Haber". The Annals of Tewkesbury record the death “III Kal Apr” in 1236 of “domina Johanna Walliæ, uxor Lewelini, filia regis Johannis et reginæ Clemenciæ”. The Chronicle of the Princes of Wales records that "Dame Joan daughter of king John and the wife of Llywelyn son of Iorwerth" died in Feb 1237 "at the court of Aber and was buried in a new cemetery on the side of the strand which Howel bishop of Llanelwy had consecrated". ¹
