Richard fitz Gilbert de Clare (died 15 April 1136) 3rd feudal baron of Clare in Suffolk, was an Anglo-Norman nobleman. A marcher lord in Wales, he was also the founder of Tonbridge Priory in Kent. Life Richard was the eldest son of Gilbert Fitz Richard de Clare and Adeliza de Claremont. Upon his father's death, he inherited his lands in England and Wales. He is commonly said to have been created Earl of Hertford by either Henry I or Stephen, but no contemporary reference to him, including the record of his death, calls him by any title, while a cartulary states that a tenant had held "de Gilleberto, filio Richardi, et de Ricardo, filio ejus, et postea, de Comite Gilleberto, filio Richardi" ("of Gilbert Fitz Richard, and his son Richard, and then of Earl Gilbert Fitz Richard"), again failing to call Richard 'Earl' while giving that title to his son. Thus his supposed creation as earl is without merit, although his status and wealth made him a great magnate in England. There is an old photo document on the Wikipedia page for Tonbridge priory which states that the priory was founded by Richard de Clare EARL of (B.. illegible) and Hertfordshire. Directly following the death of Henry I, hostilities increased significantly in Wales and a rebellion broke out. Richard was a strong supporter of King Stephen and in the first two years of his reign Richard attested a total of twenty-nine of that king's charters. He was with King Stephen when he formalized a treaty with King David I of Scotland and was a royal steward at Stephen's great Easter court in 1136. He was also with Stephen at the siege of Exeter that summer and was in attendance on the king on his return from Normandy. At this point, Richard apparently demanded more land in Wales, which Stephen was not willing to give him. In 1136, Richard had been away from his lordship in the early part of the year. He returned to the borders of Wales via Hereford in the company of Brian Fitz Count, but on their separating, Richard ignored warnings of the danger and pressed on toward Ceredigion with only a small force. He had not gone far when, on 15 April, he was ambushed and killed by the men of Gwent under Iorwerth ab Owain and his brother Morgan, grandsons of Caradog ap Gruffydd, in
