Jasper was born at the Bishop of Elys manor at Hatfield in Hertfordshire in 1429, his parents second child. His older brother, Edmund, was born at Much Hadham Palace in 1430. 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 Abbeys monks.
