Gwladus "Ddu" FERCH LLYWELYN of Gwynedd 1

  • Born: Gwynedd, Caernarvonshire, Wales
  • Married (1): 1216
  • Married (2): 1230
  • Died: 1251, Windsor, Berkshire, England

   Known in English as Gladys "the black" or "the dark-eyed".

  Research Notes:

The identity of Gwladus's mother is still a matter of debate. There is no clear contemporary evidence that her mother was Joan, and a daughter of Llewelyn and Joan could not have been aged more than about 9 in 1215. The only direct statements appear to come some centuries later. One strand of the later tradition does identify Gwladus's mother as Joan, but another says she was Llewelyn's mistress Tangwystl. 3


The Annals of Dunstable record that “Reginaldus frater eius” (referring to “Ćgidius Herefordensis episcopus”) married “Leulini Regis Wallić…filiam” in 1216. Henry III King of England granted protection to "Gwladosa filia…[L.] principis [Norwallie] que fuit uxor Reginaldi de Brausa" dated [May] 1229, issued at the same time as letters of protection to her brother David. Henry III King of England granted safe passage to "David filium L. principis Norwallier in veniendo ad regem ad faciendum ei homagium suum, et sororem ipsius David" dated 5 Sep 1229. It is likely that this unnamed sister of David was Gwladus, coming to England with her brother before her second marriage.

The Annals of Worcester record that “Radulphus de Mortuomari” married “filiam Lewelini, conjugem quondam Reginaldi de Breusa” in 1230. A manuscript narrating the foundation of Wigmore Abbey records that “Radulphus” married “Lewelinus princeps…Gwladusam Duy filiam suam”, who brought her husband “omnibus terries de Kery et Kedewyn”.

The Annales Cambrić record the death in 1251 of "Gladus filia domini Lewelini" at Windsor. 2
