Richard Marshal, 3rd Earl of Pembroke ( 1191 – 15 April 1234), was the son of William Marshal, 1st Earl of Pembroke and brother of William Marshal, 2nd Earl of Pembroke, whom he succeeded to the Earldom of Pembroke and Lord Marshal of England upon his brother's death on 6 April 1231. Early life Richard was the son of William Marshal and his wife Countess Isabel. His father's biography calls Richard his 'second-born child' after his elder brother William Marshal the younger, who was born in 1190.
