    Other Events and Attributes:

    • Alternate birth: of Bramber, Sussex, England
    • Alternate death: Sep 1211, Corbeil, near Paris, France

    Notes:

    "William was the most notable member of the de Braose dynasty. His steady rise and sudden fall at the hands of King John is often taken as an example of that king's arbitrary and capricious behaviour towards his barons." [Wikipedia]

    "William de Briouze, Lord of Briouze, Bramber, Brecon, Over Gwent, &c., s. and h. He m. Maud De St. Valery, "Lady of La Haie." In consequence of his well-known quarrel with King John, his lands were forfeited in 1208, and his wife and 1st s. starved to death in the dungeons of Corfe (or of Windsor) in 1210. He d. at Corbeil near Paris, 9, and was bur. 10 Aug. 1211, in the Abbey of St. Victor at Paris." [Complete Peerage I:22]

    "He slaughtered Seisyll ap Dyvnwal (abovenamed) and a host of unarmed Welshmen, in the castle of Abergavenny in 1175, in revenge for the death of his uncle Henry of Hereford [Brut y Tywysogian, R. de Diceto, etc.). Seisyll was owner of Castle Arnold, and is said in an inaccurate version of the Brut to have captured Abergavenny in 1172, the slaughter being dated 1177 (The Gwentian Chronicle, Cambrian Arch. Assoc, p. 137). But the better version of the Brut (Rolls Ser., p. 218; Y Brutieu, in Welsh Texts, ed. Rhys and Evans, 1890, p. 330) on the contrary, states that Seisyll was captured in 1172 by the garrison of Abergavenny. (ex inform. G. W. Watson.)" [Complete Peerage I:22, footnote (a).]

    Other Events and Attributes:

    • Alternate death: 1210, Corfe Castle, Dorset, England

    Notes:

    Also called Maud de Braose; Moll Wallbee; Lady of La Haie.

    From Wikipedia:

    "In 1208, William de Braose quarrelled with his friend and patron King John. The reason is not known but it is alleged that Maud made indiscreet comments regarding the murder of King John's nephew Arthur of Brittany. There was also a large sum of money (five thousand marks) de Braose owed the King. Whatever the reason, John demanded Maud's son William be sent to him as a hostage for her husband's loyalty. Maud refused, and stated loudly within earshot of the King's officers that 'she would not deliver her children to a king who had murdered his own nephew.' The King quickly led troops to the Welsh border and seized all of the castles that belonged to William de Braose. Maud and her eldest son William fled to Ireland, where they found refuge at Trim Castle with the de Lacys, the family of her daughter Margaret. In 1210, King John sent an expedition to Ireland. Maud and her son escaped but were apprehended in Galloway by Donnchadh, Earl of Carrick. After being briefly held at Carrickfergus Castle, they were dispatched to England.

    "Maud and her son William were first imprisoned at Windsor Castle, but were shortly afterwards transferred to Corfe Castle in Dorset where they were placed inside the dungeon. Maud and William both starved to death. [...]

    "Maud de Braose features in many Welsh legends. There is one which says that Maud built the castle of Hay-on-Wye single-handed in one night, carrying the stones in her apron. She was also said to have been extremely tall and often donned armour while leading troops into battle."

    Other Events and Attributes:

    • Alternate death: 23 Nov 1170
    • Alternate death: 28 Nov 1170

    Notes:

    "Though it was Owain who finally accepted the principle of Angevin overlordship over Gwynedd, he regarded himself as no ordinary vassal (his attitude to episcopal elections in the see of Bangor should be noted) and it is clear that it was he who gave initial direction to the policies of his successors. It was largely due to his example, moreover, that the native rulers of Wales ceased to be mere tribal chieftains and took their place alongside the great feudal magnates of the time. The praises so repeatedly accorded to his many personal qualities by contemporary poets, and indeed by several public figures who could not have been predisposed in his favour, have so genuine a tone about them that the progressive trends in all the arts of peace and war discerned in 12th century Wales, it must be concluded, were in large measure due to the fostering genius of ‘Owain the Great.’" [Dictionary of Welsh Biography, citation details below.]

    Owain married Cristin ferch Gronwy ab Owain ab Edwin. Cristin (daughter of Gronwy ab Owain ab Edwin and Genilles ferch Hoedlyw ab Ithel an Edryd ab Inethan ab Iasedd ap Carwed ap Marchudd ap Cynan) was born in of Tegeingl, Wales. [Group Sheet] [Family Chart]

    Sheriff of Hereford, 8 Apr 1173-75.

    "Briouze-Saint-Gervais (formerly Braiose), arrond. of Argentan, dept. of Orne. His descendants spelt the name Brewes. In some 25 early references to this name, not in charter latin, it appears as Breouse, Breuse, or Brewys (the last of which still exists as a surname), but never as Braose, the form adopted in peerages, for which it seems doubtful if there be any good authority." [Complete Peerage I:21, note (e).]

    "William de Briouze, Lord of Briouze in Normandy, and of Bramber, Sussex, s. and h. of Philip de B., of the same, by Aenor, da. and h. of Juhel son of Alvred, Lord of Barnstaple and Totnes. He m., in or before 1150, Bertha, 2nd sister and coh. of William of Hereford abovenamed, being da. of Miles of Gloucester, 1st Earl of Gloucester. Sheriff of Hereford, Easter 1173-1175, at which earlier date probably he already possessed the Lordship of Over Gwent. He was living in 1179." [Complete Peerage I:21-22, as corrected in volume XIV.]

    Notes:

    His brother William of Hereford, king's constable, died before 1166, mortally hurt by a stone dropped from Bronllys Tower, co. Brecon.

    Which is how the honor of Abergavenny passed to their sister Bertha and to her husband William de Briouze.

    Other Events and Attributes:

    • Alternate death: 1139

    Notes:

    "It was part of the traditional lore of the Welsh bards that Gruffudd ap Cynan had made certain regulations to govern their craft, and his name was used to give authority to the 'statute' drawn up in connection with the Caerwys eisteddfod of 1523. There is nothing to substantiate this tradition, but it is not unreasonable to suggest that Gruffudd may have brought bards and musicians with him from Ireland and that these may have had some influence on the craft of poetry and music in Wales. He may also have made some formal changes in the bardic organization. It is clear that a genuine and persistent tradition to this effect existed in the 16th century. It is perhaps worth noting that the History mentions the death in battle of Gellan, Gruffudd's harpist, in 1094." [Dictionary of Welsh Biography, citation details below.]
