Richard de Clare, 3rd Earl of Hertford  Richard de Clare, 3rd Earl of Hertford, lord of Clare, Tonbridge, and Cardigan (–1217), was a powerful Norman nobleman with vast lands in England and Wales. Richard was the son of Roger de Clare, 2nd Earl of Hertford and Maud, daughter of James de St. Hillary. More commonly known as the Earl of Clare, he had the majority of the Giffard estates from his ancestor, Rohese. He was present at the coronations of King Richard I at Westminster, 3 September 1189, and King John on 27 May 1199. He was also present at the homage of King William of Scotland as English Earl of Huntingdon at Lincoln. He married (c. 1172) Amice Fitzwilliam, 4th Countess of Gloucester (c. 1160–1220), second daughter, and co-heiress, of William Fitz Robert, 2nd Earl of Gloucester, and Hawise de Beaumont. Sometime before 1198, Earl Richard and his wife Amice were ordered to separate by the Pope on grounds of consanguinity. They separated for a time because of this order but apparently reconciled their marriage with the Pope later on. He sided with the Barons against King John, even though he had previously sworn peace with the King at Northampton, and his castle of Tonbridge was taken. He played a leading part in the negotiations for Magna Carta, being one of the twenty five sureties. On 9 November 1215, he was one of the commissioners on the part of the Barons to negotiate the peace with the King. In 1215, his lands in counties Cambridge, Norfolk, Suffolk and Essex were granted to Robert de Betun. He and his son were among the Barons excommunicated by the Pope in 1215. His own arms were: Or, three chevronels gules. Richard and Amice had children:
