Sources disagree on the name of the mother of Gruffydd, some say it is

Llewelyn Fawr ap Iowerth, Prince of Wales was born in 1173 in Dolwyddelan, Gwynedd, Wales . He was the son of Iorwerth Drwyndwn ap Owain Gwynedd <p40.htm> and Marared/Margaret . He and Tangwystyl Goch had a liaison producing children before Llewelyn married Joan Plantagenet. A liaison or marriage has been mentioned between Llewelyn Fawr ap Iowerth, Prince of Wales and Gwenllian assumed to be in Llywelyn's younger days. He married Joan Plantagenet, daughter of John I Plantagenet, King of England and Agatha Ferrers , in 1205. He died of natural causes on 11 April 1240 in Aberconwy, Gwynedd, Wales . He was buried after 11 April 1240 in Aberconwy Abbey, Aberconwy, Gwynedd, Wales .

Llywelyn II, was also known as "The Great," Prince of Gwynedd (Northern Wales 1194-1240), Prince of Wales, and Ruler of All Wales (1203-1240). Llewelyn was the son of Iorwerth Drwyndwn ap Owain Gwynedd and considered to be the true heir of Iorwerth's father, Owain Gwynedd, the son of Gruffudd Ap Cynan of the House of Aberffraw (Geoffrey Plantagent, father of Henry II of England, is another descendant of the House of Aberffraw). In 1230, Llewelyn had William de Breos (father of his daughter-in-law Isabella) hanged "for excessive familiarity" with his wife Joanna. Llewelyn spent most of his life fighting off his father-in-law, King John, and trying to free Wales from English domination. He also spent a good deal of time fighting with the other Marcher Lords of Wales over territory. There are some wonderful historical novels about this period in Wales and the romance and lives of Llewelyn and Joanna, including King John of England, written by Sharon Kay Penman.
