Roger was a son of Richard de Clare, lord of Clare and Tonbridge, and Alice/Adeliza of Chester, daughter of Ranulph de Meschines, 1st earl of Chester, vicomte de Bayeux.
Roger succeeded to the earldom when his brother Gilbert died without issue. In 1164 he assisted with the Constitution of Clarendon. From his munificence to the Church and his numerous acts of piety, Roger was called the 'Good Earl of Hertford'.
About 1150 he married Maud de St.Hilaire du Harcouet, daughter of James de St.Hilaire, seigneur de St.Hilaire du Harcouet and Aveline. Roger and Maud had seven children of whom two, Richard and Aveline, would have progeny.
Roger died in 1173, and was succeeded by his son Richard. Maud married William d'Aubigny, 2nd earl of Arundel, and they had a son William who would have progeny. Maud died in 1193.
Earl of Sussex, Earl of Arundel; b. 1165; went on Crusades in 1218; d. bef 30 Mar 1221 in Cainell near Rome; bur. at Wymondham Priory, Norfolk, England; m. Mabel Kevelioc. [Charlemagne & Others, Chart 2929]
He married Mabel 2nd daughter of Hugh (LE MESCHIN surnamed KEVELIOC), EARL OF CHESTER, by Bertrade, daughter of Simon, COUNT OF EVREUX in Normandy. She, in her issue, was (1232) one of the four coheirs to her brother Ranulph (surnamed BLUNDEVILLE), EARL OF CHESTER.
Originally he was one of King John's favorites. He was with the King at Runnymede, and surviving from the wars that followed there is a royal writ, dated at Colchester on 24 Marcy 1216, ordering the sheriff of Norfolk and Suffolk to make timber available to the constable of Rising 'to fortify the castle of the Earl of Arundel.'
The earl went over to the rebel cause in the June of that same year, joining the baronial party opposing the king in 1216 after the sealing of Magna Carta. According to the Barnwell annalist, when the barons met in London (1216) to plan the division of England between them, they assigned to d'Albini the government of Lincolnshire. However, in July 1217 he returned to the allegiance of the boy King Henry III. Thereafter he went on crusade and was present at the fall of Damietta in 1219, but died on his way home, near Rome in 1221. [Castle Rising, p. 15].
