John Hastings, 3rd Earl of Pembroke was the son of John Hastings, 2nd Earl of Pembroke and Anne Manny, 2nd Baroness Manny.
Background
He succeeded his father as an infant in 1375. He married Elizabeth of Lancaster the daughter of John of Gaunt, in 1380, but the marriage was unconsummated (he was 8 and she 17 at the time of the marriage) and was annulled after she became pregnant by John Holland, whom she subsequently married.
Career
He was also Baron Abergavenny. Richard II held his Christmas court at Woodstock Palace in 1389, and the seventeen year old Pembroke took part in the Christmas sports, including jousting. Pembroke was described by the chronicler as being mourned by the common people as well as the nobility, by reason of his kind and generous nature.
