Bertha's father Miles served as Constable to King Stephen of England. He later served in the same capacity to Empress Matilda after he'd transferred his allegiance. In 1141, she made him Earl of Hereford in gratitude for his loyalty. On 24 December 1143, he was killed whilst on a hunting expedition in the Forest of Dean.[10]
Marriage and issue
In 1150, Bertha married William de Braose, 3rd Lord of Bramber (1112–1192), son of Philip de Braose, 2nd Lord of Bramber and Aenor, daughter of Judael of Totnes. William and Bertha had three daughters and two sons, including William de Braose, 4th Lord of Bramber.
In 1173, Bertha's brothers all having died without issue, she brought the Lordships and castles of Brecknock and Abergavenny, to her husband.[10] Hay Castle had already passed to her from her mother, Sibyl of Neufmarche in 1165, whence it became part of the de Braose holdings.
In 1174, Bertha's husband became Sheriff of Hereford.
Maud de Braose, married John de Brompton, by whom she had issue.[12]
Legacy
Bertha died on an unknown date. She was the ancestress of many noble English families which included the de Braoses, de Beauchamps, de Bohuns and de Ferrers; as well as the Irish families of de Lacy and de Burgh.
