SIR JOHN LUMLEY, brother and heir, born 2 February 1382/3, was already a knight at the time of his brother's death. On 20 March 1404/5, although he had not then proved his age, he had a patent for livery of all the possessions of which his father and brother were seised on the day on which they made forfeiture, the Earl of Somerset having surrendered his patent thereof, and John having done homage and fealty. Upon his petition in Parliament, November 1411, he obtained a declaration under the Great Seal, with the assent of the Lords Spiritual and Temporal, that he was restored to the name and capacity to hold the possessions of his late father and brother, notwithstanding the corruption of blood between himself and them. He took part in the French campaigns under Henry V, and was slain at the battle of Baugé in 1421.
