From Wikipedia - Llywelyn the Great :

Another daughter, Gwladus Ddu (c.1206-1251), was probably legitimate. Adam of Usk states that she was a legitimate daughter by Joan, although some sources claim that her mother was Llywelyn's mistress, Tangwystl Goch.[64] She first married Reginald de Braose of Brecon and Abergavenny, but had no children by him. After Reginald's death she married Ralph de Mortimer of Wigmore and had several sons.

Gwladys married Reynold de Braose, son of William de Braose 5th Lord de Braose and Maud de St. Valerie of Haie, before 1221 in Wales. (Reynold de Braose was born about 1178 in <Bramber, Sussex>, England, died on 9 Jun 1228 in Brecon, Brycheiniog [Breconshire] (Brecknockshire), (Powys), Wales and was buried in Priory Church, Brecon, Breconshire, Wales.)

Gwladys next married Ralph de Mortimer Lord Mortimer of Wigmore, son of Roger de Mortimer of Wigmore and Isabel de Ferrieres, in 1230. (Ralph de Mortimer Lord Mortimer of Wigmore was born about 1190 in <Wigmore, Herefordshire>, England, died on 6 Aug 1246 in Wigmore, Herefordshire, England and was buried in Wigmore, Herefordshire, England.)
