Elen ferch Llywelyn

Elen ferch Llywelyn (c. 1207 – 1253) was the daughter of Llywelyn the Great of Gwynedd in North Wales by Joan, Lady of Wales, the natural daughter of King John of England.

Elen married John of Scotland, 9th Earl of Huntingdon, in about 1222. He died aged thirty in 1237, and she was forced by King Henry III (her mother's half-brother) to marry Sir Robert de Quincy, the son of Saer de Quincy. Their daughter, Hawise, married Baldwin Wake, Lord Wake of Liddell. Hawise's granddaughter, Margaret Wake, was the mother of Joan of Kent, the first English Princess of Wales.
