Humphrey was born. The Visdelou family held manors in Oxfordshire, Suffolk and Berkshire. Humphrey Visdelou was granted a fee in the later parish of Talgarth by Bernard de Neufmarché after the latter's conquest of Brycheiniog [became known as Brecon] in 1093. This fee later became known as Trewalkin , and took its name from Humphrey's son Walkelin Visdelou.2
- [S1415] Powys Local History Encyclopedia: The Visdelou family held manors in Oxfordshire, Suffolk and Berkshire. Humphrey Visdelou was granted a fee in the later parish of Talgarth by Bernard de Neufmarché after the latter's conquest of Brycheiniog in 1093. This fee later became known as Trewalkin , and took its name from Humphrey's son Walkelin Visdelou. During the civil war between Stephen and Matilda Walkelin seems to have sided with the king, but his overlord, the lord of Brecon (probably Earl Roger of Hereford) supported the Empress. Roger apparently confiscated Trewalkin and gave it to Brecon Priory. Walkelin may have been influenced by Stephen's strength around Oxford where his most valuable manors lay.
Walkelin Visdelou died sometime after 1148, leaving three sons to inherit his English estates, Humphrey (who had his Berkshire estates confiscated by Henry II for killing a knight), Walkelin and William. [G.R.] - http://powysenc.weebly.com/venables---visdelou.html
- [S1416] Bernard de Neufmarché, Bernard de Neufmarch [1050-1125] was "the first of the original conquerors of Wales." He was a minor Norman lord who rose to power in the Welsh Marches before successfully undertaking the invasion and conquest of the Kingdom of Brycheiniog between 1088 and 1095.
Bernard was the son of the minor and incompetent Norman baron Geoffrey de Neufmarché and Ada de Hugleville, and he was born at the castle of Le-Neuf-Marché-en-Lions on the frontier between Normandy and Beauvais. His ancestors on his mother's side had founded the town of Aufay south of Dieppe on the Scie, while his paternal grandfather, Turketil had served the young William II of Normandy as a guardian and was killed in that capacity. On his mother's side he also descended from Richard II of Normandy.
By the time of his death around 1125, Bernard had established a flourishing borough around his castle of Brecon. Henry I had married Bernard's daughter Sibyl to Miles Fitz Walter, the High Sheriff of Gloucestershire, in 1121 and passed a significant portion of Bernard's honour to him as a dowry, including Hay-on-Wye Castle. According to Giraldus Cambrensis this was because Mahel de Neufmarché the son and heir of Bernard had mutilated the paramour [illicit lover] of his mother. In vengeance his mother, Nesta, swore to King Henry I that her son was illegitimate. Henry was therefore able by law and custom to pass over Mahel and give the land to his friend and confident Miles Fitz Walter with Bernard's legal heiress in marriage. - http://en.wikipedia.org/wiki/Bernard_de_Neufmarch%C3%A9
