Henry arranged for the best priest to educate them intellectually and morally. Sometime after March 1442, Jasper and his brother were brought to live at court. In 1442, their half-brother the King began to take an interest in their upbringing. They were also permitted servants to wait upon them as the King's half-siblings. She was the sister of William de la Pole, 1st Duke of Suffolk, a great favorite of Henry VI, and was able to provide Jasper and his siblings with food, clothing, and lodging.

Jasper, Edmund, and possibly their sister were put into the care of Katherine de la Pole, a nun at Barking Abbey, in Essex, from July 1437 to March 1442. Catherine's last child would be born in 1437, mere days before her own untimely death on 3 January.Īfter Catherine's death, Owen Tudor was arrested and sent to Newgate prison. Vergil also mentions a daughter who became a nun, but little is known of her. According to Henry VII's personal historian Polydore Vergil, Owen was taken and raised by the monks to become a member of the order, living under the name Edward Bridgewater until his death in 1502. His younger brother, Owen, was born in 1432 at Westminster Abbey, when the Dowager Queen was visiting her eldest son and her water broke prematurely, forcing her to seek the help of the Abbey's monks. His older brother, Edmund, was born at Much Hadham Palace in 1430. Jasper was born at the Bishop of Ely's manor at Hatfield in Hertfordshire in 1431, his parents' second child. This connection added greatly to his status in Wales.

Through his father, Jasper was a direct descendant of Ednyfed Fychan, Llywelyn the Great's renowned Chancellor. He was the half-brother to Henry VI, who, on attaining his majority in 1452, named Jasper Earl of Pembroke. Jasper was the second son of Owen Tudor and the former Queen Catherine of Valois, the widow of Henry V of England.
